Me and my girlfriend had a short trip to Valencia this 1st week of May. Although short, stayed only 3 nights, the place was very nice, exactly what we needed. The host was amazing. Very quick responses every time and very open to help and offer suggestions when asked. Water bottle in the room was very much welcomed since we were veery dehydrated after the flight and car ride, so thumbs up.
Something to keep in mind, but this is something normal for Valencia, the climate is very humid, so after using towels to dry yourself, I would suggest putting them near a window, otherwise the air will feel a bit iffy. But again, this is not particular to this place, it's not their fault.
Anyways, long story short. Had a great time, place was close'ish to the center, host was nice, and would come back any time.
