Hard to beat this location in Valencia! Not only is it right in the heart of Russafa, but it's also on one of the few quiet streets around with no bars below it so there is not much noise at night (which I imagine is not the same with many other apartments nearby!)
We stayed for 5 weeks and the apartment was perfect for our needs. Not a huge living room and small kitchen, but still it was comfortable enough for 2 of us and we really appreciated the high speed wifi (300+Mbps) to get some work done and small TV to relax. My only feedback really is the kitchen supplies were very basic and cheap quality, but ultimately we made do with it and the location of the apartment for restaurants, bars and getting around the city made up for it.
Hector was easy to reach and everything went smoothly!
