Francesc and Natalia are great hosts! They were helpful during our stay of 4 days, although we didn't see them a lot. If we needed any help, they were easy to contact and they tried to make it as comfortable as possible for us.
The location of their flat is great! very easy to find with navigation on your phone. We took the metro from Barcelona airport to hospital clinic and after that it's a 500m walk to their place, where Natalia was waiting for us to arrive and explained everything we needed to know for our stay in their flat.
The room is clean and cosy. Bed is comfortable. Bathroom is next to the bedroom and very clean. Towels are provided. That was all we needed for our citytrip. Francesc and Natalia weren't home most of the time, so we had a lot of privacy.
The flat is close to a lot of touristic hotspots like Placa Universitat, Placa de Catalunya and Placa Espanya. All are in walking distance. There are a lot of restaurants and little supermarkets nearby.
I would definitely recommend this place, if you are looking for a place to stay for a citytrip!
