For my trip in Valencia I was 4 days in this apartment. Here my feedback in different areas.
Apartment: The apartment was very clean. Everything you need was available. The bed was comfortable. There was a lot of information about the city.
Host: I didn't meet Claudio (host) personally. But he was always available and responded very quickly to my messages. The check in was made by his friend Angel. Claudio and Angel are both very friendly.
Location: The apartment is very good and central located.
Conclusion: I can highly recommend the apartment and Claudio as the host.
Garcias again and see you.
