We stayed with friends in Edu's flat during period when Marathon took place in Valencia. And we liked his flat very much! The flat is very cozy, with spacious hall and two bedrooms, where everyone could have their own space. Also there is a nice terrace.
The flat has all the amenities you might need, so it makes you feel like you are home.
The hosts are very polite, and hospitable.
Edu is not only quick in responses, but also was nice to give us a bunch of recommendations and suggestions on where to shop, where to eat, where to go, etc.
The supermarket is really very near around 400 meters from flat.
It was 4-4.5 km away from the park, from the start of the Marathon route. So it was good to jog to the place at the day of the Marathon. Also, the flat is just in 7-8 mins walking distance from the metro station. And around 2 km walking distance from the main street full of shopping boutiques and restaurant and cafe alley.
We liked our stay very much and highly recommend you Edu's place.
