This was a really great place to stay for accessing all the main points of Barcelona. We only used public transportation 7 times over four days, mostly on the metro. But we walked everywhere. Josep greeted us and was really kind and helpful. The apartment is nice and roomy, with place to relax - a sofa and chair - plus a place to eat. The bed was comfortable, the shower is nice hot water and good pressure. We are tall, so we couldn't use the loft and it was a little hard to walk around in the kitchen because of low ceiling. But that wasn't too bad.
One small problem is that there's not really much to cook with, so if you plan to go to one of the many markets to buy local food and cook, you may find that difficult.
We loved our stay, and felt safe the whole time. It's a wonderful base for enjoying Barcelona.
