We had a wonderful stay at Nereas place. It is a fabulous apartment in a beautiful style. Warm, cozy, charming and spacious. It has everything you need - a big kitchen, a comfy bed, heaters (in the winter), a bath tub, towels, and even a little breakfast. The Old Town and the Guggenheim Museum were within walking-distance. Just be aware that the neighborhood is not the best and it gets noisy at night (only in the living room, NOT in the bedroom! I slept perfectly fine there and I am a light sleeper) - we never felt unsafe. There are inexpensive grocery stores around and it is very close to the train station. Nerea was a sweetheart and even let us check in a bit earlier. We would come back anytime.
