The apartment is very stylish and there is plenty of room for 2/3 people. My son and I were very comfortable staying here when visiting my brother who lives in Madrid. The facilities in the apartment are very good and it was spotless. There was some confusion on how to enter the building on arrival, but due to the quick response of the owner this was soon sorted out.
The proximity of the apartment to the Metro is perfect and everywhere is so easy to reach on foot anyway. Malasaña is a very vibrant area and there are plenty of lovely bars and restaurants to choose from.
There is plenty to do, we hired bikes and spent an afternoon cycling along the river. Retiro Park is a lovely place to relax and a great place to parakeet watch! There are plenty of shops, both on Grand Via and in Malasaña itself. Great place in a great city!
