We were staying at Sergi's apartment in April 2018. The apartment is very big, with 3 bedrooms and 2 bathrooms and showers.
The apartment is clean with everything you need to stay in Brcelona for a week.
The apartment has a wifi and the building has an elevator.
The apartment is located in a quiet neighborhood, a 5 minute walk from the metro - excellent location !!!
And Sergi ... very Courteous and always available to any question and willing to help always.
Very highly recommended
