Carlos is an amazing host with plenty of attention to feel welcome (chocolats, drinks, etc). The flat is even better in real and well located. The flat is bright, quiet, with plenty of space, well equiped and the terasse is amazing. The area is lively with lots of places to to go out for a nice drink and tapas. Nice places are walking distance from the flat such as Gran Via, Retiro Park, PLaza de Mayor, etc.
Carlos was very helpful when I needed information and was very reactive.
I highly recommend this place. I have already recommended it to all my friends.
Muchas gracias Carlos for this charming flat and your time.
