Location is amazing - right in the heart of Chueca near tons of cafes and restaurants, and walking distance from museums and sights. Very safe neighborhood. The restaurant across the street - Bocaito - was the best meal of my trip. Mercado San Anton is also a few blocks away.
The space was also great - clean and stylish in a cute older building. The a/c did not work when I was there but Maria provided a stand-alone one, and the apartment stayed pretty cool.
Would certainly stay here again!
