We really enjoyed our stay at Mercedes' apartment.
It is very well located, minutes from the main transport links to/from airport and beaches (train station, metro), and at walking distance from the city centre.
The apartment is really nice, superbly furnished and very clean. The terrace is fantastic, with a wide overview of Valencia. Exactly as advertised in the website.
Mercedes was really helpful and fast in replying to our emails.
We really recommend staying at Mercedes' in Valencia.
