We stayed at Aitana and Miguel's place for one week in the summer and I can highly recommend it. It was a great overall experience, the hosts were very responsive and the appartement itself was really great! Awesome location close to the beach and everything you needed was right there. The place itself ist designed very carefully and has all amenities you need. The powerful AC was a big plus in summer. And also the bus and metro to the old city center of Valencia ist almost at the doorstep. We would definitely stay there again when visiting Valencia!
