We had a lovely time in the apartment. As already being said, the Saturdays were very noisy at night. But it was not a real problem for us. The owners live nearby and are very willing to help you with anything, you might need.
Valencia is a beautiful city. Streets were cleaned every morning. We run a lot in the 'river-park', visited the city highlights and took our car for exploring the surrounding area. We parked our car safely at the railway parking place and paid €75,00 for two weeks. It's a 10 min. walk from the apartment.
