I really like this place because it's around the city centre, in other words, ideal for people who loves to explore. We can walk around to visit all the famous places of Madrid and amazing for who loves to spend the nights out! Good for single people or couples without children.
Pros: excellent location, great flat, calm area, shops and restaurants around and exactly the same that it's showed in the pics.
Cons: it's necessary to fix some things in the flat, punctuality and communication with the staff, the cleaning is a bit poor and "paper" walls.
Anyway, nothing that could destroy your trip.
