Wow!
If you're in Valencia, you should stay here.
Sergio's apartment has the feel of a very cool boutique hotel.
The design of the place is amazing- LOADS of space in the integrated lounge/kitchen, equipped with modern furniture and kitchen facilities as well as the coolest designed bathroom I've ever seen!
The lovely balcony is a bonus, again the elegant design has been thought about very carefully.
Although we didn't meet Sergio, we were well looked after by his lovely neighbour Belén who was very communicative both before and during our stay and kindly met us at the metro on arrival to ensure that we didn't get lost!
The location is spot on. Not far from Turia gardens (you can do a good bike tour through here) and a 10mn cab ride from the Futuristic ciudad de las artes y ciencias which feels like something from Space Odyssey 2001!
A very comfortable stay. My flat will feel very old fashioned after staying here..
