My stay in Valencia at Ester's place was really convenient for me. I was able to check-in late even though my plane landed very late and I arrived in the city only after 1 am. The location is very nice since one is very quickly at the Metro and at the city center. There is no great view in the flat since it is at the ground floor, but in Valencia one anyway needs to go out and visit the city and the beach, so no reason to stay in. Ester was also very helpful. The airline delayed my suitcase for some days, and since I couldn't be there when they delivered it, she helped out and was there to receive it for me. That was really great and it made my day.
Moreover, it was nice to have two separate large beds in two rooms, since I traveled with a colleague from work. So we didn't disturb each other when we were up late. One of the rooms is rather small and there is not much space to put the suitcase, but the bed is comfortable and also the common area is large. So I would definitely recommend staying at Ester's place!
