Location, location, location. Close to all types of public transportation (buses and subways), restaurants and coffee shops, as well as just a few blocks from a beautiful shopping center and other attractions. The apartment is located in a quite safe neighborhood.
Although the pool is much smaller than what the pictures show, it's ok for a fast cooling off. Ok for 1 person or a young couple for a short stay.
Thanks Valentina for trying to help with towels and blankets :-)
