A very good place to book!! Very close to the underground line Anton Martin. Very good connection with the main attractions of the town like Gran Via, Plaza de Cibeles (can be reached with 10 min walk through the Paseo del Prado where you visit the famous museum), Plaza Mayor ecc. The flat has everything, in a very cool block full of pubs abd restaurant (you can have breakfast just going 5 metres on the left in Calle de las Huertas where a cafe is alwais open and with awesome pastries). I suggest to book here. Everything is fantastic!!
Ps we left our luggage over the time of leaving, Mari Paz has been very gentle!
