Overall we enjoyed our stay, would recommend with minor adjustments.
Pros
+ location - central and very close to bakery and super markets and bodegas! most importantly, just a few steps from the L1 red metro line which made traveling around Barcelona very convenient
+ terrace - we enjoyed the terrace so much. Beautiful view of Barcelona!
+ full kitchen - though we did go out to eat a lot, it was fun to buy groceries from the boqueria market and make food at home to enjoy on the terrace with wine
+ great hosts - we interacted mostly with Toni. He was very responsive and friendly.
+ wine - greeted with a bottle of wine
Cons
+ uncomfortable beds - the mattresses have Springs sticking out which made it very hard to sleep through the night. normally this would be fine for a short stay but not good for those who are adjusting to the time zone and staying a while. None of us slept comfortably.
+ towels - only provided one for each person for the whole week. The host offered for cleaners to bring more but we were not comfortable with cleaners in the space unaccompanied. It would be nice if they provided at least 2 towels each person for the whole week
+ sheets - sheets didn’t seem to be washed, there were stains on some of them
