We stayed at Laura's in the begging of April. The place is situated very central, so you have everything in a 5 mins walk, supermarket, mall, restaurants. Colon, metro station is 2mins walk , a straight line to the airport, 25mins. Laura is very communicative and very helpful and the place has everything you need from pans to toiletries. She also left for us a welcoming basket with water, fruit and biscuits, that was very nice, after a long flight.
As a negative, the flat it was very cold. There is an electric heater you plug in and the AC, but in the night it was still cold , so make sure you pack some good pyjamas. I would also say maybe the place needs a bit of touch ups here and there. Over all, a good experience in Valencia.
