Alex was great. I've been traveling to Barcelona annually for about 6 years and his apartment was definitely nicest, easiest apartment I've stayed in.
Great location - a few blocks off Ramblas so quieter at night which is good, but still in the heart of and walkable to everything. Having the metro station a block away was incredibly convenient.
The place is clean, updated and we loved how the living room/kitchen was separated from the bedrooms. Folks were able to sleep while others were hanging out.
