Our stay was wonderful. Some of the reviews prior to booking noted that the staff was high on hospitality, which didn't disappoint. Carla and Andrea were extremely helpful and communicative prior to our arrival. Carla and Alvaro were our points of contact during our stay, maintaining that hospitable and helpful approach. Alvaro even went so far as to arrange childcare for our two children so my wife and I could spend a day exploring the city without them in tow!
Location-wise, it is about a 10 min walk to Las Ramblas and the Gothic Quarter (the more touristy areas). For those who would like to be a bit away from that would find this accommodation perfect. We found ourselves a bit more in the 'locals' area, which we enjoyed as it gave us perhaps a bit more of a feel for the 'real' Barcelona culture, not just the touristy parts.
The area is still extremely walkable with tons to do and see and lots of great places to eat.
