We really loved staying at Belén's place. The building was gorgeous, and the apartment was exactly as pictured. It was walkable to all kinds of things right outside the door. There was plenty of space for our family of four to stretch out after long days of running around Barcelona. Check-in was remarkably smooth with the virtual keys, and Belén was very responsive with communication from start to finish.
Belén left snacks and recommendations for places to visit in the neighborhood that were very helpful. The washer and dryer were also very helpful, as we were traveling with only carry-on suitcases and had packed light. The apartment was very clean and full of light. We loved the view from the little balconies.
The only negative I would mention was we ran out of hot water after only three of us took (quick) showers. We worked it out by having one of the kids take a shower at night instead.
We thought Belén's place was beautiful, comfortable, and roomy. Perfect location.
