At arrival, the host gave us a lot of information about Valencia which helped a lot for our trip. We stayed 11 days, so we could use some info what is going on. Previous guest also left behind some info in the manual.
The apartment was great, really no remarks on this, Only some unlucky problem with the elevator that caused some smell issues in the building. Luckily this was not in the apartment itself.
The neighborhood is the best. Very well located when you travel from the airport to the apartment with metro, and you are at the edge of the old city, so visiting Valencia by foot is very easy. You are also close to a bus stop (line 2) if you want to go to the beach that only costs 1.5 euro per person.
The busses and metro are also the ideal transport if you want don't feel like walking. You can reach everything.

A tip if you want to go to Albufera, If you take the bus, you can stop just before the split between el palmar and el perrelo. Here you can take a boat that takes you around the lake to spot some birds and take a closer look on the park. Then if you want to go to el palmar, make sure you take the right bus, because at that point, you have 2 busses.
