First of all the positives, Gina was very welcoming and the location in Recoleta is very convenient. It's close to Recoleta Cemetery and Las Heras Subte.
Unfortunately there were a number of issues. I had booked the room for a month because I did a Spanish course in BsAs. Upon arrival I was given a different room to the one I booked, which was much smaller. The other room was occupied by a friend of Gina and when I asked her about it, she explained that the room was too noisy. I eventually moved into the other room and it was true, the room was noisier as it was right next to the living room, and you could hear the TV and people talking until late at night. Gina also has a dog which often barked in the middle of the night, because it appears he doesn't really like strangers. Generally it has to be pointed out that the flat is next to a very busy road and it's very noisy even at night.
Whilst the place was generally very clean, there was a problem with ants in the kitchen. At one point there was also no water for 3 or 4 days in the morning or evening, so that it was impossible to wash or shower.
Lastly upon arrival I was told that I was not allowed to bring friends over, which I understand, but it would have been nice to mention that in the airbnb rules, not AFTER arrival. When I asked to have a friend stay over Gina reluctantly agreed, but was then trying to charge extra even though the room was advertised for 2 people. It also has to be said that Gina doesn't speak English and whilst this was good for me as I was trying to learn Spanish, it did make communicating very difficult.
