We had a great stay at this Airbnb, would recommend it to everyone!
The unit is located on the 5th of a building, and don’t worry, there is a elevator! You can find the exact building location by searching StayTogether Barcelona, the entire building hosts short term rentals, with a management office located on ground floor. We felt very secure as there is security cameras everywhere, front door needs security card to get in. Staff was also extremely friendly and helpful, they showed us around when we first checked in, provided bed linens for our extra guest, management office also left out embrellas for guests to use on rainy days. The place is also very clean and well maintained, everything looked exactly like the photos, we love the Juliette balconies! Location is excellent as well, we are right beside a subway station, with many shops and restaurants around, and also in walking distance (10-15min) to La Ramblas.
