My sister and I had the pleasure of staying in Uxue's flat. Uxue was there to meet us when we arrived. She is so lovely! She provided us with all the basic information we needed to enjoy our stay in Barcelona. And she was attentive throughout our stay. She even provided space in the fridge and pantry for us which was a nice touch.
The flat is exactly as pictured: bright, spacious, and comfortable. The location is as central as you can get! There is so much to see and do within walking distance.
As we stayed during the weekend, there was some street noise at night. We were there in August, hence, we had to sleep with the windows open:-) I imagine it won't be an issue during cooler nights with the windows shut.
Overall, we had a lovely stay and we would stay there again.
