I chose Paco's place based on the reviews and the attractive roof terrace (although I didn't think we'd be able use it in December, but we did!) and we all felt immediately at home - which is rare. Russafa is definitely the nicest area of Valencia to stay in and every bar or restaurant we tried was excellent and lively. Next time we're in Valencia in the weekend I'll reserve a table at one of the restaurants along the beach because that's obviously the thing to do on a Sunday and booking is essential.
We drove in from the south and that was very easy, the only trouble is finding a parking space.
We didn't meet Paco, but he responded very quickly and helpfully to any questions I had. All in all a wonderful place to stay.
