The plus point is location, which is near to a lot of bars and restaurants. Public transports are pretty accessible provided that you know how to navigate around.
For late check-in, I recommend messaging your arrival at least 35-45 min before. As we had informed 10 min before leaving the airport on taxi, we still had to wait for another 35 min for the check-in.
There are 6 steps before reaching the elevator, so I would not recommend booking if you have very heavy luggages, which unfortunately I had, as Barcelona was our last location for Europe trip.
It was almost impossible to leave the windows open over the night as there is too much noise from the traffic and people on the streets. However, it is acceptable when the windows are closed.
For the single bed bedroom, there’s no air conditioner, so it may get a little warm.
Overall it’s a pleasant stay in Barcelona.
