Awesome location. 4 blocks to Plaça Catalunya 2 blocks from Pacig de Gràcia. A small market right across the street. Great communication with host. Questions were answered promptly. Air conditioning worked well and beds were large and comfortable.
Only downside is that building has some noise in hallway and stairwell ( due to a Hostel on one of the upper floors, I think). Noise was disruptive in the front 2 bedrooms at night and in the morning. In the back bedroom, it was very quiet. Bring earplugs.
I would certainly stay here again on future visits to Barcelona.
