Excellent location - within a 5-10 minute walk to Placa de Espanya, with all its amenities (including Metro)
The building is in a very safe location of Barcelona (right across the street from a major high-end hotel).
There were some noise issues in the building, but this is beyond the control of the owner. You will get a decent night's sleep - but if (for whatever reason) you need to sleep during the day, this could present a challenge.
There is a small elevator in the building which helps when moving luggage, etc.
The other residents of the building are friendly.
All in all, a good value for money!
