We had a good stay with Marco & Felipe!
We stayed in the smallest room of their apartment in Valencia.
Positive: Fully equipped kitchen, spacious living room, washing machine, cleanliness, access to the beach in around 10mins of walking, host were really supportive
Cons (depending on your plans):
Reaching to the city center is quite far, this room + bed are quite small for two people, and only one bathroom in the apartment for up to six residents (“traffic jams” in the morning) - all manageable of course.
