UPDATE: I got to stay another month in my current rental, but need a new place for October 1st. I have seen a few, the ones in dollars directed towards foreigners have been too expensive for what they are, I think, but now there is one that I like. It is just blocks away from where I live, it is nice and newly renovated, and while it is furnished, it is still a lot closer to the "blank canvas" I was hoping for: there is nothing on the walls, no curtains, no decorative lamps etc. and the furniture is new and not too bad. With some pillows, blankets, lamps and pictures it can be really cool I think. It is advertised as a one bedroom, but actually has a small cuarto de dependencia with its own little bathroom, so that is great for guests. It has two small patios and the kitchen is big and nice. It is through an agency, which is a little annoying, and with expensas and commission included it comes to around 9500 pesos. Quite a bit more than I pay now, but also better standard.
The only thing that has me doubting is the fact that it is on the ground floor, and internal, which means it doesn't have as much light as I like. The kitchen and bedroom has pretty good light from the patio, but no direct sunlight as far as I can tell. The living room has a small patio with not much light.
I guess I am using this post to analyze my pros and cons - and what I am seeing is that I am clearly too picky, jaja! I want quiet - but light; I want a low floor (I prefer not having to use the elevator all the time) - but light; I want my same neighborhood; I want to be able to decorate; I want an old building, I want outside space... Wow, I never claimed to be easy going but I am terrible! I think I need to decide what is most important: quiet or light...
Oh, and quick question: is it normal for agencies to require two months rent as deposit for a six month contract? Seems like a lot, I know they all ask for one, but two seemed a lot to me.
