If you provide the name of the street and the round number of the block (600 for example) where your future apartment is located, other members will be able to tell you if it's actually in Palermo Soho.
Ads (and individuals) that falsely claim that an apartment is in Palermo Soho or Recoleta are fairly common.
I thought about posting the street name and block, but decided that security trumps other considerations. And it was the cab driver who took me there that said it was Soho, not the owner. She just said Palermo.
My new landlady and her hubby seem like really nice people. I went over to look at it once, she and her mother were there and were very nice. Then went back Saturday and met her and her other half to make a deposit.
They were very hospitable, offered me tea and cookies, and we sat talking for a good half hour before they brought up business. I let them set the pace of the conversation, suppressing my aggressively American instinct to "cut to the chase", because I know in some cultures it's very rude to skip the small talk and bring up business too soon. All in all, it was a very pleasant visit, and I got a seriously positive vibe from them both.
I could have had a place for less in San Telmo, but it was a monoambiente on the 9th floor, it had no oven, and there were only two burners on the stove. This place in Palermo has a separate bedroom, a small oven with full stovetop, and is within probably-survivable jumping distance of the ground.
But security may be an issue, granted. Maybe I can find a sword cane on mercado libre...
