I wonder what the contract provisions are for recovering costs through withholding money from the rent, based on receipts for money spent (and obviously based on having sent notice, etc)? I believe there is something related to this in the "national" contract, and a section of a contract that attempts to override the "national" contract (standard contract by law? Whatever it's called) is null and can't be enforced. I'm too lazy to go find my contract right now to verify, but I believe that the standard contract has provisions for this type of situation. I'm pretty sure that the notice (and penalty payments) required to vacate, for example, is waived by law if the owner does not maintain certain things that are his responsibility, rendering the apartment unlivable.
One question - are your hot water pipes for kitchen/bathrooms functioning? I have a friend whose building got cut off by the gas company, related to the new restrictions because of what happened in Rosario (I think that's where it was?) and he has been without hot water and heat for three months now. He made a deal with the landlord to keep the lease in place but is only paying the building expenses and living in a temporary place in the meantime.
If space heating is the only unlivable issue you have, it can be resolved, but hot running water is a necessity in winter - at least in modern times, in a modern city.
I love the apartment I'm in right now. Having lived here for 8 years and knowing how hard it can be to find just the right place at the right money (my biggest thing is the size-to-price ratio - we now have five of us and I work at home!), I'd deal with a certain amount of little things to keep this place.
In fact, I have. Things like the shower glass (not a shower door, but one of those half-length glass "walls" that hinges) in my master bathroom about to fall off at the top - the owners had it "reattached" before we moved in (apparently it had fallen off at some point) and the top hinge is coming unbolted (the anchor bolt is pulling out of the wall), since we first moved in. I've asked them to fix it a number of times. We've been here three months now and they still haven't managed to get anyone out to even look at it. They're the nicest of ladies (sisters) but they don't get very much done. I'm calling someone out next week and footing the bill myself and will talk to them about reimbursing me through withholding some of the rent money, even over some months if needed (maybe the sisters don't have a lot of money for repairs on the apartment - their responsibility but my problem).
To top it off, our building heater is too hot for me and I have no way of controlling it (doesn't heat the floors, but there's some kind of radiator behind a grill that is fed by hot water pipes in the walls) except opening a window somewhat to try to counteract the heat. I'm sure a problem you would prefer to have, but personally I played ice hockey for 17 years and I guess I prefer cold to hot any day
We have a number of little things like that, which were supposed to be taken care of before we moved in but were either done in a half-assed manner and have become issues again, or were not taken care of. But it's 170 sq meters for $1000 USD a month, with three bedrooms, an office, and a large living and dining room. Very pleasing aesthetically. And in Recoleta - except for two years in Garin, near Pilar, I've lived in Recoleta my whole time here and that's where the majority of my friends live. It's a beautiful apartment and I figure I have to do what I have to do to live in it and try to get re-compensated afterwards.
With two year leases, moving can be expensive (relatively, for here - much cheaper than in the States, to be sure) and a pain-in-the-ass. I fill my 170 sq meters completely with furniture I've bought over the years. Finding the near-perfect place where you want to be, at the right price, can be very time consuming.
I don't move lightly.
One thing I've learned here is that it is what it is. It can be very difficult to stand on your rights and depend completely on that to make things right in any kind of timely manner. Sometimes you just have to do what you have to do to be happy.
I'd buy some heaters if the landlord isn't responsive to do so, before you freeze. Remember, even if you move, I doubt you'd be able to just find a new place and get into it overnight, unless you are talking a temporary rental to move into immediately - and the move is likely to be more expensive than the heaters - and in a couple of months winter will be over until next year...
I'd discuss withholding money from the rent after having officially notified the owner of your complaint. I believe you have the right expectations about the probability of the pipe situation getting worked out in two weeks, and finished within a couple of days of work starting, but I've been pleasantly surprised here as well and you never know. If you end up with some heaters that you don't need, they're not outrageously expensive and you can probably find someone to buy them come next winter.
You are on a guarentia/2 year unfurnished rental? Just asking because I'm paying 1100 USD/month for a furnished tourist rental -a PH - 90 sq meters in Palermo Hollywood. Trying to figure out what the current rental market is and if it's worth trying to move into a non-tourist situation or not. It's such a pain to move and to have to furnish an entire place just may not be worth it at the end of the day- even though I have a lot of kitchen supplies, some living room chairs, TV.
