Staying at Edu's Airbnb was a really great experience. It is extremely easy to get to from the airport (a simple ride on the metro followed by a 5 minute walk from the station). The flat itself was incredibly clean and very stylish and very comfortable. Plus the aircon was a Godsend in the heat.
Edu had been in touch before our journey to Valencia to provide us with really helpful tips and places to visit in Valencia (both locally and city wide), so we felt that we were very prepared once we got to Valencia.
Edu had also provided maps and other local tips for our stay. His recommendations for where to eat were spot on and the food was amazing (especially the local bakery which we ate at every morning of our stay).
The flat is very close to the city centre (roughly about 10 minutes walk, or an easy metro or taxi ride if you're feeling tired).
I'd thoroughly recommend staying at Edu's flat on your visit to Valencia, and plan to hopefully stay there again when I visit Valencia in the future.
