We were 7 people visiting Valencia over the weekend. The apartment was great, the communication with Victor was really great and he was also very flexible with Check-ins and Check-outs. Also a plus is that we had 3 keys, which is really important, when you are a group like us!
The only thing that might be useful to know, is that in front of the building is a huge place for soccer games. It is used a lot during the weekend, which is cool to watch from the balcony when you are in the mood. But when you are very sensitive to noise, then I would recommend to take earplugs with you, just in case.
