Maribel's flat is very well located in the El Born / El Gothico area right next to great restaurants and bars and short walk to port/beach.
The room we had was of a good size and although the bathroom was shared it was very clean and was next to the room - we were able to use to as we pleased.
Maribel and Hedwig were very welcoming and made us feel at home during our stay.
The only downside was we felt as if we were slightly imposing on their privacy as their bedroom is only separated from the corridor by a curtain. However, they are very relaxed so it was not a big issue.
We would recommend the flat for its great location and pleasant hosts.
