A friend and I stayed at Isabel's apartment for 3 nights. She was very accommodating, dynamic, and communicative. The place was comfortable and located near 2 subway stops (Gran Via and Chueca), many bars, shops, and restaurants. I would definitely stay here again if I visit Madrid again! Big plus that the apartment had a washing machine! Isabel is also very trustworthy. I accidentally left my passport behind and she returned it to me in a timely manner.
