The unit was in good condition and was very conveniently located, within easy walking distance of multiple metro lines, shopping, and restaurants.
The AC died after the first night, which was not ideal during the heat, but can happen anywhere. We also did not receive a welcome kit, which had things like laundry soap and the like, but was only a minor inconvenience.
The building has a small number of lockers for free bag storage after checkout which was great.
Overall, was a great option for any length of stay in Barcelona.
