The apartment was great. Clean, tastefully decorated, very warm and cosy and had everything we could possibly need. Gaby was very helpful and spoke English (which is not a given, in Madrid). The Malasana neighbourhood is indeed the best place to stay. Every sight is closeby either by foot or via Tribunal metro station which is only steps away from the apartment. The district has dozens of cafes and restaurants as well as three squares where you can enjoy coffee and drinks, outdoors. I would definitely book this apartment again if I decide to visit Madrid again!
