Mik was a really helpful host. All communication was flawless, he shared tips with us and he even has a shared map on Google Maps of recommended places in Barcelona, which are very useful as local tips.
The apartment was exactly as on photos, very clean and very welcoming. There was everything we needed for our stay. The bed in the bedroom was very comfortable and we fit with the 3 of us without problems.
The location is not in the city center, but it's only a 10 minutes walk to the beach, which was very helpful during those hot days. Public transportation to the city center was very easy, there were metro, tram and bus stops right next to the building, with 25-30 door-to-door times to anywhere in the center.
I also rented a bicycle, there was a safe place for locking them in the yard of the building and with a bicycle it was only 20 minutes of a nice stroll to the city center.
