I definitely recommend to choose Juan's apartment. The place is just wonderful! It is very nice and clean, modern, with plenty of light and all commodities included. The neighborhood is nice, quite and very colorful. There are a lot of grocery stores and restaurants nearby, public transport is just 5 minute walk away (metro and tram). The apartment is very close to Cabanyal beach and a couple of bus stations from La Malvarossa beach. Overall, the place is absolutely great and the city of Valencia is very charming!
