We stayed with 5 friends in this appartement, which is a lot smaller than expected based on the photos, an therefore not very convenient for this amount of people (though it advertises for up to 6 people!). The one bathroom is very narrow with mold on the floors. Living room and bedrooms are small, beds were quite good but unfortunately by arrival we found hairs that were not ours. When we arrived, one of the curtains was broken. Location is great in the area of Poblenou with bars, restaurants, metro station and beach close by. The appartement is not really an AirBNB as it is rented by a company, you have to pick up the keys in the center, which is about a 30 minute travel by public transport. We were able to store our luggage at the office during our last day.
We enjoyed the location of the appartement, but would not recommend staying here with more than 3-4 people, and hygiene and maintenance should definitely be improved.
