This was a wonderful stay, the only downside being that it only lasted for a week.
Rosa & Xavi's home is spotless clean, well decorated and very comfortable. They are awesome hosts who will go to great lengths to ensure you have the best stay possible.
I could easily work from my room (with a desk, fast & reliable internet, little noise from the street), which had a single bed, some storage space and A/C.
The shared areas include a living room (with couches and a dinner table), 2 bathrooms and a kitchen with all the appliances to cook (micro-wave, electric oven, gas stove, large fridge, kitchenware) and laundry (wash and dry), all in very good condition.
I've briefly met a few easy going people staying for a few weeks/months, as there are 3 other rooms in the apartment. The location is also a big plus, in the lively Gràcia neighbourhood, with transport, supermarkets and other commerce within walking distance.
