Ulises and his apartment are equally wonderful! My girlfriend and I stayed for 5 nights in October and found it to be THE perfect place for enjoying all that Madrid has to offer. The location is incredible - a 5 minute walk to a metro stop, 10 minutes from El Plaza Mayor, and in the center of a great local neighborhood with tons of cool restaurants, bars, shopping, etc. The apartment itself was awesome - clean, well-appointed, quiet (some of the best sleep we got in Europe), and comfortable. Ulises even gave us maps, recommendations, etc. to ensure we were well taken care of. We would not hesitate to stay with him again, and anyone thinking of visiting Madrid would be foolish not to give him a chance.
