Valencia is great! Jorge is very helpful he offered to bring us to apartment from the airport.He was asking if we are good in appointment and need help with anything. Great host I think.
Apartment is older, but you have everything that you need there.Its a good spot.I felt safe there.
For this apartment my tips are bus 93 that goes straight to the beach and leaves from Ave del Cid ( around the corner). To rent a bike use Proservice, they have very comfortable bikes there. For groceries you have Aldi that is on the opposite site on the left when you are leaving the apartment and other shop 5min walk when you go to the right and turn right and go straight (open till late).
Valencia is huge it was easy to be confused looking for places Google maps are a great help.
