The location is fantastic, best area I’ve stayed in in Barcelona so far - close to the metro, easy to access most places and walkable to many great restaurants/cafes/bars/shops - really close to Lidl if you need shopping, and a generally a really safe feeling neighbourhood.
The apartment is comfortable, smooth check-in, and great AC for the hot evenings, it easily slept 3 of us - however no basics are provided, be prepared to buy handwash/dish soap/cloths, and basic cooking things. Also the buildings’ walls are quite thin, be prepared with ear plugs if you’re a light sleeper.
This doesn’t outweigh the convenience of the apartment for a short city stay in Barcelona, but just some things to be prepared for.
