My wife and I along with another couple stayed in Christian's place for one night while in Valencia. Christian was there to greet us even though we didn't get there until around 23:30!
The apartment was on the second story, so not too many steps. It was very clean with comfortable beds, air conditioning, plenty of space to spread out, and a spacious shower area. It is located minutes from the "green belt" around Valencia and very close to a Valencia bike rental spot.
Christian was also incredibly accommodating as we changed the plan on him a bit the second day. He was very gracious and helped us out on our second day travel plans! We could not have been more pleased!
