This apartment is more like an apart-hotel than an apartment itself. The one we stayed was really very nice, modern and clean. It is located in a beautiful modern building and they have 24h reception with someonw always ready to support you. Towels and linen were of high quality and extremely clean. The apartment has cold/warm air conditioning, so we had a nice temperature, although it was quite cold outside during our stay.
It is important to notice, however, that the host is an enterprise that manages several apartments in the building and allocates it to the guests according to the availability. So, the apartment you receive may not be exactly as shown in the pictures. In our case, for instance, the first apartment they gave us was on the 7th floor, with a very ugly view on the back of the building and no cute wallpaper as shown in the pictures. We were so disappointed... After we strongly complained (as the view announced in Airbnb was basically the main reason for us to choose this apartment) they have moved us to the 35th floor, with an incredible view as shown in airbnb. They have even upgraded us to a two-rooms apartment, as the studios with a view were not available anymore on our dates. So, in the overall, our experience was very positive.
Another point to mention is that, although Airbnb shows it as if its location was in Recoleta, this is not really right. The apartment is in the city centre. Having said that, the location is really nice. In the building you have a Starbucks and a great Peruvian restaurant that we really enjoyed in a small break from the great Argentinian meat (as well as other nice bars, cafés and restaurants). It is 200m from Calle Florida, 300m from Galeria Pacifico and within walking distance from Puerto Madero and the Obelisco. The Recoleta cemitery, instead, is around 1,6 km away... We personally really enjoyed the location, but if you are planning to stay at the Recoleta neighbourhood this may not be exactly the place for you.
