It is indeed a very nice place and previous reviews are perfectly accurate. If you are ready to climb some stairs, especially on arrival with your bags, it is a very good choice for exploring Barcelona. It takes 10-15 minutes to walk to the centre, say La Rambla. We used hop-on-hop-off buses and walked. Never used public transport in a week. And there is a wonderful Abirradero pub and tapas bar nearby. Perfect craft beers and excellent service.
And again, many thanks to Irene - she is a perfect host.
