Our trip to Barcelona was great.
The best thing of the apartment is the view of the balcony!!!
The apartment is a little bit outside of the middle of Barcelona near Park Güell but you can reach everything by the metro station Vallcarca.
The negativ aspect was that the Check-in was not on time! We waited until 3pm although the information for the check-in was 2pm. Even though, we mentioned that we‘ll arrive in Barcelona in the morning and we got very late a reply for the arrangement to Check-in.
