This apartment is excellently located, high up near the top of this tall apartment block with views over western Valencia, and just a couple of minutes from the well-connected Beniferri metro station (currently less than 1 Euro to the city centre with a 10-journey Bono ticket and less than 5 Euros to or from the airport door-to-door). It's also close to the tram for getting to the beach. There is an underground car park, but only for use of longer-staying guests. There are dozens of cafes, bars, restaurants and clubs to choose from in the street below and immediately surrounding districts.
The shared facilities are also outstanding with a terrific outdoor pool with large jacuzzi in the hot summer months (June-Sept) and all-year-round gym, changing rooms and indoor swimming pool (cap required here), as well as single-sex saunas, open for 3 or 4 hours each day and two padel tennis courts (for doubles only); there's also a kiddies' paddling pool and play area.
Although the rooms are fairly small, as in most modern city apartments, it is well equipped including a filter coffee maker though not an espresso machine. The TV is basic but the wifi is good, so streaming is easy on your own small screen and there are plenty of sockets.
Throughout my month-long stay I never met either the owner Javier (who was abroad) or his local representative Peter, and as a result a few minor problems on arrival took a little longer to resolve by phone/email, but the complex has a 24-hour security porter's lodge and I found it enormously helpful to take time to build relationships here.
As it turned out, I think I made a v good choice of AirBnB apartment in Valencia for my needs, and this length of stay qualified for a good discount, so I believe it represented very good value for money.
Thank you Javier and Peter.
