We had a good stay in Barcelona 85 days). The apartment is very conveniently located in a nice area, close to good restaurants, small grocery shops, metro, walking distance to Park Güell etc.
Unfortunately the apartment was not that clean, my kids were not able to use the 2 beds in the small room as they were badly squeaking at the smallest move and woke us up several times on the first night - we ended up putting the mattresses on the floor. This is definitely not a penthouse and it is not an apartment for 6 people (max. 4). We inquired about hand washing soap in the bathroom and was told that it is not a hotel and it is not standard to get any (never heard this before in an airbnb location). However, each of us (5 persons) received sample size aluminium packed shampoo. Additionally, sample size cleaning kit (dishwasher, washing machine) plastic foil packed is provided. These go against the claim of caring for the environment to be found on the wall.
This and a few other aspects made us feel happy to leave the apartment in the morning and only return late in the evening. However, it can be improved and I hope the hosts will do their best for the next guests.
