I would highly recommend Charo's place! The room is lovely and the entire apartment spacious and clean. It is situated in a very nice, vital neighbourhood with plenty of nice bars, restaurants, and shops and it is also close to everything one is looking for in Madrid - Gran Via, the museums, the main plazas! Charo is a very warm, carrying and hospitable person! I enjoyed my stay at hers (of almost 2 weeks) a lot and would always return. It made my stay in Madrid really great!
