I really, really recommend staying at Claudia's apartment in Buenos Aires. I had an amazing stay over the last month for so many reasons.

Pros:
- This is a big apartment building (over 20 units, I think), so you actually have some flexibility in where you stay. I've been in AirBnb rentals where the owner only has 1 unit, so that's where you're stuck.
- Along those lines from the 1st point: I originally had an apartment facing the main street and the associated traffic (I'm a light sleeper, so I was waking up at night), and asked if I could move to the back of the building. Claudia set up the switch (even when she was on vacation out of the country), and I was in the new apartment the next day. And then I was able to get plenty of beauty rest :)
- The building is close to *everything*. If you're staying in Buenos Aires, Palermo is the trendy neighborhood with tons of restaurants, shopping, nightlife, etc. And it's safe, like really safe - I go walking at night, sometimes after midnight or 1am, and never feel unsafe.
- The street it's on is relatively quiet for Buenos Aires
- Good value for the neighborhood and how close you are
- Everyone in the building, from Victor the repairman to Yolanda the cleaning lady, is super friendly. I honestly feel like I made friends here, and it was cool practicing my Spanish with Victor.

Cons:
- I'm not sure if I can really think of any - if you're a light sleeper like me, then the street noise might bother you. But again, that's fixed with an apartment facing the other direction. And besides, you're in a huge city with 5MM people, so there's going to be some noise.

Claudia - thank you for your hospitality, and for the great stay!
