We stayed in the unit with 8 people. ( 2 families of 4) The unit was very clean. We like the setup. It was very spacious and had plenty of privacy even with a large group. It is located in a bit quieter part of town closer to Sagrada Familia. We were happier with this. We felt the location was very convenient easily accessible via bus or metro. There are also very good cafes, restaurants, and markets close by.
The property manager was also very helpful in accommodating us to store our baggage prior to checkin as we arrived in Barcelona much earlier than the checkin.
We were very happy with our stay. We would stay again and definitely recommend,
