The apartment looks exactly like in the pictures and it is very cosy and home-like! It is very clean and offers probably anything you need: from bedsheets, table items and hair dryer to candles, umbrellas and touristic maps.
The apartment is also well located, within 10-20 min from all major touristic places and very close to the metro station - 5 min.
Our main contact person (out of the 3 owners) was Ricardo and he was very helpful and nice with everything we contacted him about.
If we were to return to Madrid, this apartment would definitely be one of our accomodation options!
