It was amazing to stay in Marga's house. I stayed there for a week and everything was perpect...! Bed, Wifi, bathroom .. even the paella that Marga made for me. About the location, if you get the bus n. 7 or n.9 from the city centre , you can get to the Marga house straight within 20 min. Furthermore, Marge will welcome you and she is amazing host. she made me feel like she's a mother and I'm in my home. I really appriciate her for everything she gave me and I want to recommend you this place for your time in Valencia. It will be really good for you!
