I traveled to Buenos Aires for three weeks in January 2020 with my 12-year-old daughter. The hosts for this listing were responsive and gave us all the necessary information without overwhelming us with extra details. We encountered long lines at the airport, so we checked in slightly later than they expected, and they were very understanding about that.
The apartment is modern and comfortable and the kitchen was stocked with the basics in terms of dishes, pots & pans, etc. The beds were comfortable (firm mattresses) and the apartment and building were very clean. The air conditioners worked perfectly, which is key in the summer, and you can control each room's temperature separately. I especially loved having our own clothes washing machine, and a large drying rack was provided.
The living room and 2 bedrooms all have huge, beautiful windows (floor to ceiling in the bedrooms, both with sliding doors to the balcony; there's also balcony access from the living area) and the morning sun comes in bright. We reported an issue with one of the sliding doors to the balcony, and Welcome2BA sent someone to fix it; he was pleasant, prompt, and efficient. The only thing that didn't work properly and wasn't able to be fixed during our stay was the TV (it only showed one channel, MTV), but we didn't have time to watch it anyway, so we didn't miss it.
The location is ideal. It's about 3 blocks south of Plaza Italia, which has subway and bus stops, and beyond that are the botanical gardens, Ecoparque, and Bosques de Palermo. Grocery stores, restaurants, shopping and nightlife are all located within a few blocks, yet up on the 7th floor of this building it was really quiet. The rooftop pool is small but refreshing and it was fun to be up there with a city view. We also enjoyed the beautiful view from the apartment's balcony and windows; the apartment is on the back side of the building (not the street side) and we could see a large swimming pool and garden area that belonged to a neighboring building. It was fun to people-watch from there.
All in all, this was a very pleasant home-away-from-home. We would stay there again!
