It is a very nice apartment in a city center with all the necessary amenities inside. The location is great, near to several metro stations, shops, restaurants, etc. The apartment is baby-friendly as the building has an elevator and you can rent a baby cot in advance. Take into account that the flat is very small, and for more than 3 people it might be a little uncomfortable. One of the bedrooms has no windows and when you close the door it gets very stuffy inside, so the only way is to always keep the door open. Overall I recommend the apartment to everyone who travels to Madrid for a few days, thank you very much for a pleasant stay!
