We( my husband and 2 daughters of 15 and 13)had a very pleasant stay.
The apartment was clean and it had wifi, that made the girls really happy.
The neighborhood is really nice. Everything you need is nearby, nice restaurants(we can recommend Cannibal Raw C/Almirante 12!)all the nice shops and of course from walking distance Prado, Thyssen and the beautiful park El Retiro.
