absolutely recommended. This apartment is on a fantastic location and within walkable distance to a lot of places and transportation in Madrid is easy and efficient. Check-in was simple and quick and the place was clean and very well equipped. We even had a complimentary bottle of wine! That was great. The only small issue we had was with one of the air conditioning units which started leaking, informed the manager and nothing was done. Nothing major at all, but eventually the wall might get damaged.
In any case, this is a great place at a very reasonable price and we totally enjoyed it. Absolutely recommended.
