The good points of the rental were that the room was really well located for both the old town, the cathedral, the town hall square, the central market and the metro from the airport. It was also walkable to the modern shopping area. The room itself was clean and a good size and there were lots of thoughtful things in the house like umbrellas for rain and beach and a beach blanket and towel. There was also water, coffee and tea provided and other amenities as detailed. There is both good aircon and heating.
The less good things were that Ana is unresponsive, since I mailed her a few times in English and Spanish to find out if I could drop off my luggage early, and it was only when Laura, who did the check-in, got in touch with me 24h in advance that I was able to arrange this. The good thing is that Laura was very responsive. The flat is in a good location but suffers street noise at the front and bad water pressure in the shower - however these are common Valencia problems.
