This is a great apartment for one person or a couple. It quirky but I think that's to be expected given the location which is perfect (right in the old town of Valencia). Maybe note this is third floor with no lift and a narrow staircase but it didn't bother us at all.
Check in is easy with a lockbox outside, the flat has a fully equipped kitchen and nice shower/bathroom and enough storage for all your things.
Surprisingly quiet considering how central it is. Would recommend to anyone visiting Valencia and wanting to stay in the center.
