I just returned from a month-long stay at Laura and Lucia's apartment. It was AMAZING! Both Laura and Lucia are wonderful, caring people. They responded quickly and had great suggestions. The apartment was great and had everything I needed, including a washing machine which came in very handy. I was working remotely while I was there and the wifi is fantastic -- I never had any issues. The location of the apartment is unbeatable. Valencia is a very walkable city and you will be in the middle of everything. Also, there are several bus stops practically outside the door and a metro stop at the corner; the train station is less than a 10 minute walk.
If you are planning a trip to Valencia and Laura and Lucia's place is available, BOOK IT!!! I can't wait to go back.
Laura and Lucia - thanks again for everything.
