I had a great 5-night stay at Nelson’s apartment. Nelson was lovely, very responsive to messages and really helpful. The room was perfect for me. It was clean and there was plenty of space and a good en-suite bathroom. The apartment is located, right next to Sol and Gran Via with lots of restaurants, museums and other things near by, but it’s on a side street so quiet at night which is ideal as I’m a light sleeper. I will definitely stay here again next time I am in Madrid!
