When we arrived, Claudia gave us a map where to find the nearest supermarket, nice places to eat, the bus stop and the metro station. That was really convenient! The appartment is close to the sea (+/- 10 min walk) and it looks exactly like the photos. It was also very clean and the terras is a nice place to have breakfast (which you can buy in the supermarket: 1 min walk).
Claudia works very close to the appartment and she helps you when you have a question (eg. buying bus tickets).
You can walk from the appartement to the 'Ciudad de las Artes y Ciencas' (+/-15 min walk) and you can take the bus or metro to the city centre.
I really liked our stay in the appartment en Claudio and Emilio are very good hosts!
