We found the apartment a good size for the 5 of us (4 adults and 1 child). Especially appreciated 2 full bathrooms and the washer/dryer. The place is right above an intersection and may not be suitable for light sleepers sensitive to street noise (however, sleeping in the sofa bed in the living room was away from street noise and quiet)
Our travel dates clashed with the Mobile World Congress in Barcelona, we had to pay a high rate per night (more than what we paid for the previous nights while staying at a 5-star hotel in BCN). So I would unfortunately have to say value for money is not great, but that was our choice.
We appreciated the responsiveness of the host, even on a Sunday to deliver extra bedding for us.
Thank you for hosting us in Barcelona!
