The place location is perfect, close to 2 underground stations. We were with a kid, and right in front of the building there is a playground, and a square with green, where kids can run. Minimercado is about 50 meters from the apartment.
The apartment is completely what u can see on the pictures, one living room + kitchen and one bedroom with quite new furniture. Bathroom is small, but OK, WiFi works well.
Marisa's English is good, she answers quickly, and answers the phone. She helped to solve our problems in a day.
There were to problems: we asked for baby bed in advance but it has arrived only for the second night, so I had to sleep on the couch first night. We were there in March, the weather was cold, and the heating wasn't satisfying for the baby (only one gas fire), so we asked for another electric heater not to freeze at night.
