We had a wonderful week in Evelin and Gisele's Gracia flat. As a family of 6, we were concerned that quarters might be tight, but we felt very comfortable and relaxed in this beautiful place. The flat has all the amenities we needed - from washer and dryer to hairdryer and coffee maker that makes wonderful coffee (make sure you purchase the smallest nespresso pods, not the bigger ones - they don't fit! :) ).
The Gracia neighborhood is vibrant, welcoming and very friendly. The restaurant and shopkeepers were happy to chat with us (almost everyone speaks english which made it easy for us!) We stayed in Gracia as the neighborhood was preparing for the annual festival (Festes de Gracia), with neighbors out on the street making and hanging elaborate decorations. It was great to come home each evening and see the progress of their process.
If you're a light sleeper, you may want to close the windows at night as the neighborhood stays up late and gets up early. We'd definitely stay here again!
