The apartment is really easy to get to from the airport. The subway is directly connected to the airport and from there its a single 30 minute ride with the subway, and it's only a ten minute walk from there.
We were greeted on arrival and shown the apartment. The apartment was neat and clean and the kitchen, bathroom and bedroom were very complete. There was breakfast available for the following morning wich was really helpfull on a sunday.
Maria and Esther were also very helpfull and quick to answer questions, they also arranged a taxi for us for when we had to leave.
The beach is a short walk from the apartment and travelling through the city is easy to do with the subway (But the most fun is renting a bicycle, especially if you're planning on visitting Albufera) There are multiple supermarkets nearby. The neighbourhoud was pretty nice and quiet, we had no problems with noise in the night.
