We stayed in the apartment for two months (February and March) and were very happy there. Dorothea, the owner, was away during our stay, but her caretaker/maid, Marcela, was extremely helpful and responsive. The location of the apartment is great and convenient to everything. There are two good supermarkets within easy walking distance (2 blocks and 6 blocks) as well as a good laundry within two blocks of the apartment (clothes are washed, dried and folded for you with same-day service). The building itself is very quiet (hardly any noise from the neighboring apartments during our stay) and there is very little traffic noise from the street below. Air conditioning and wifi worked well for us during our stay. Communication with the owner (Dorothea) and with her caretaker (Marcela) was easy and fast before and during our stay. We had one small maintenance issue at the beginning of our stay that was taken care of immediately/same day. The closest subway/subte station is about 6 blocks away and there are numerous buses to all areas of the city within 2-3 blocks. The bus system is fairly easy to navigate if you have a mapping app on your android phone like googlemaps. Taxis are plentiful and inexpensive. The area is safe and we felt very comfortable walking around at night. Final note about communication: some fluency in Spanish is a big help in communicating with the caretaker (Marcela). Overall, we loved our stay at Dorothea´s place!
