We had a wonderfull time at Susana's place. The host (whom was not Susana) was friendly and kind. He took the time to show us the house and gave us more information about where to go in Valencia and how to get there.
The house was big enough to fit 9 adults. And if we needed anything we could call him. It was only a 5 minute walk to the beach, the beautiful boulevard, a large supermarket, different busstations and a bike rental. That way everything you want to see is not far away. My advice, rent a bike. It is by far the best way to see Valencia!
