Great location to visit the city!
I am from Valencia, but living outside the country since more than 8 years. I come often to visit family and friends and this year we decided to get a flat instead sleeping at someone else place.
Emilio's flat is probably one of the best located flats in Valencia if you want to visit it intensively:
It is in a calm and silent pedestrian street, but with one of the main streets of the city around the corner, together with a huge grocery, shopping malls, the Colon subway stop and taxi stop areas.
From there you are at 15 to 20 minutes walking from most of the main points of interest of the city. You can reach Ruzafa, El Carmen, Turia and Plaza de España by just having a walk.
Emilio was very friendly and ready to provide everything we might have needed, he gave us some updates about the city and where to find new places and good restaurants.
We are quite sure we will repeat next time we visit Valencia!
