We stayed in several spaces throughout Madrid and Barcelona, and Nikohls was one of the best for quietness and proximity to fun things like restaurants, bars and even downtown and all the best art museums and main sites to see. We are also vegetarian and this place happens to be close to some of the best veggie food we've ever had! (El encomienda, Santa y Pura, Oveja Negra) So that was a very fortunate twist of luck. Thanks again, Nikohl! it was a nice place to stay on our very first experience to Spain.
