The flat is located very conveniently close to the local beach. The house does not have an elevator and the flat is on the 4th floor, which was no problem for us, but is to be considered for mobility impaired people. The flat is spacious, however the bathroom is very small and can only be entered by one person at a time. The shower has a curtain and the shower basin is not I stalled well (it moves when you step on it and is partially broken). This leads to the fact that we had to mop the floor immediately after any short shower.
There is a well equipped kitchen but no dishwasher.
Very practical: a washing machine/dryer is in the flat - great for washing your beach towels and bathing stuff.
There are towels for use in the flat, but understandably they should not be taken to the beach.
David is a very good host, was super friendly, speaks perfect English and always helpful and responsive.
We had a great time in Valencia.
