Carmen is super friendly. She had left a useful guide in the apartment which helped us a lot. And also messaged us to ask how we were doing and if we needed anything.
The apartment is very cosy and has anything you need. We were working during our stay in Madrid so we were looking for a place where it would be convenient. This apartment has lot of cosy places to work with laptop. The kitchen is really cool, we cooked a lot.
Also the location is great. You can reach center by bus or metro but we preferred walks. It takes about 20 minutes and all the Madrid joys are at your palm. We recommend this place 100%!
