Marian was very helpful and friendly as a hostess. Even though we did not speak each other's language (english - spanish), we managed to understand each other. The apt is located in penthouse' basement and lacks sunlight, but this undoubtedly must be a great advantage in summer. All rooms are small but very well equipped. Located very conveniently on a quiet street, just 5-7 minutes walk to the nearest metro stations, Diego de Leon and Ventas.
All in all, we've spent a very nice week there and would definitely recommend it.
