As described, very clean apartment and very close to the city. Hosts are nice and considerate.
The positives: very centric flat, walking distance to everything. Near metro station and hundreds of local restaurants. It is a very diverse and interesting neighbourhood. The flat is very clean and comfortable. The kitchen is fully equipped and has good appliances. All in working order. Comfortable beds and clean bedsheets, etc. Great value for money.
The negatives: lots of stairs. The TV wasn't working while we were there but it seemed like a fault from the cable company (bad luck for us).
Would recommend this flat to anybody going to Barcelona.
