We had a great time in Peter's apartment with six people. The apartment was fine for 6 as we were elsewhere a lot. The beds were good and it was nice that there were two bathrooms with private toilets that we could use.
The dining room / kitchen was almost closed off from a large window to the outside / or to a balcony. There was a large TV there. We ourselves have brought a chromecast with us to sometimes watch our own content. The location is superb. I come to Valencia more often and for me this is the best place to stay. It was also nice that there was no noise pollution.
We also rented bikes from solution bikes. We could attach the bicycles to special bicycle racks. These racks were at the Torres de Serranos. About 2 minutes walk.
