Flat in Mislata a neighbourhood next to Valencia. It has all the necessary in it because I live in here :)
You can get with public transport everywhere in Valencia. 10min to city center, 30min to ciudad de las artes y las ciencias, 40min to the beach.
You can also use my bike if you want because usually it gets more handy to use the bike in the city rather than the public transport. If you need more bikes I can let you the keys to the storage room where you can find a couple more.

There's actually more than the city, from here you can go to plenty of towns in the surroundings of Valencia as Xàtiva, Xàbea, Moreia, Bètera, etc.
