I have stayed in 5 different Airbnb's in Valencia and this one is the best location for everything we needed. I would happily stay here again.
The flat is within about 5 mins walk of 3 metro stations including Alameda which is one of the best connections in the city and can take you to Marritim-Serreria where you can then catch a tram and be on the beach in 25 mins. Alternatively, you can head in the other direction on the metro and be in Xativa next to Valencia's main train station and the heart of the city in 5 mins. It also has a direct link to the Airport (extremely useful!).
If you prefer to walk, it is maybe 20-25 mins walk to the heart of the city, or about 30 minutes to walk down the beautiful Turia park to the City of Arts and Sciences.
We visited the Mestalla stadium to catch Valencia CF playing a La Liga match and the stadium is at the end of the street, just 5 mins walk from the apartment.
For groceries, there is a Mercadona supermarket just 100m from the apartment and smaller bakeries and fresh fruit and vegetable shops even closer.
The apartment itself is located on the 8th floor and has an elevator. It has a spacious living / dining area which is decorated in a modern Ikea style. The pictures are very accurate. The kitchen had everything we needed for eating at home and included a Nespresso machine. The only thing we couldn't find was a kettle.
Bathrooms were well equipped, with a decent shower, toilet, bidet and sink.
The main bedroom is very comfortable and spacious and there are spare duvets in the cupboards. There is a smaller bedroom with 2 single beds and the sofa in the lounge converts into a sofa bed.
A few small things that could improve...
We only had one key, 2 would have been really useful.
The lock on the main bathroom door was not working
A couple of door handles were loose.
Despite these small points, I would definitely recommend Borja & Teresa's apartment!
