Elena was an absolute pleasure to communicate with and stay in her perfectly located flat! The easiness of check in and check out especially when we arrived super early from the United States was greatly appreciated. Overall we felt this was a 5 star place and experience. If I had to pick any suggestions for improvement it would a more comfortable mattresses and a king bed in the main room. There was an unpleasant smell in the second bathroom. Elena communicated very quickly with me to run the water. The smell could have been from it not being used much. That did help but it never went away completely. Her suggestions for place to eat were wonderful and we fell in love with Madrid. Looking forward to return to Madrid some day soon and stay with Elena again for sure!
