I had a fantastic stay at Alf's place! It is well connected to public transport with a number of metro stops within walking distance. The bus to the airport is also within walking distance as well as the main train station. I slept very well as the room was quiet and dark with the blind down at night. The bathroom was clean and modern. Alf was very welcoming and friendly, check in was great and Alf was flexible with check in and out times. I would definitely recommend his place and will stay again when I'm next in Barcelona!
