My girlfriend and I stayed here overnight at the end of our trip. We got in around 10PM from San Sebastián and Julio met us at the apartment to check us in. He explained the unit to us and gave us recommendations on where to find food as well.
Julio is very kind and the apartment is beautiful. We wish we could've stayed there longer. The location is a bit further from the central part of town, but with the metro you can get around easily. Retiro park is also close by.
