Nice apartment in a quiet area, close to Sagrada Familia, the metro line and plenty of inexpensive bars and restaurants to have a bite to eat. On arrival, they looked after the luggage while we went to see a bit of Barcelona until our apartment was ready, at which point the staff showed us a map and recommended various places to visit and good restaurants (which was appreciated!)
There was an issue with the shower in our apartment, unfortunately as there was a bank holiday there it didn’t get fixed before we left, inconvenient, but we managed just fine.
All in all, I recommend Albert’s place.
