The apartment is huge and in a perfect location. The subway is quite close and the beach is in walkable distance, great supermarket is nearby. Airconditioning is working fine, only a pity, that there is none in the kitchen with all the appliances producing heat. Internet fast, only in the kitchen the signal is weaker, but it still worked for us. While we had some issues in the beginning (e.g. broken toaster), Isabel was quick with fixing them.
Overall, we stayed in the apartment for almost a month and really enjoyed our time in Valencia. Thank you!
("only" 4 stars because we stayed in Gran Canaria right before and it was just touch better.. and 4.5 is not an option)
