We spent 3 weeks in this place and I believe it's just perfect both for a long and a short stay. The location is superb - you can easily walk to most city attractions, and there are plenty of shops nearby, not to mention the City of Arts and Sciences. We enjoyed the walks in the park almost every day as it's so close to the place. The flat itself is really cozy and homey - we just felt like living at home. The kitchen is well-equipped and the fridge is quite big to contain lots of food. I wouldn't say it is spotlessly clean, but it I was clean enough for us. There is a separate bedroom, which was a plus for us, as I sometimes like to stay up. The host is super friendly and helpful. I strongly recommend this place and I believe it's a perfect choice for any visitor.
