Juan is a really nice guy who actually paid our drinks at his nearby favourite bar when we arrived 2 hrs early. He communicated with us through a translator app which caused some hilareous moments.
The apartment is even better as described since the kitchen was already filled with water, wine, cookies and coffee. And then some. All sorts of kitchen appliances and cooking pots were present. All rooms were spotless and quite modern.
You could find everything you need for a day at the beach or a rainy day in the apartment . Even games for kids.
The location is at walking distance of the Ciutat de les Arts i les Ciències and the nearby bus stop is a 5 minute walk. You can get to the beach in about 30 minutes with public transport. There is free parking in the streets around the apartment.
All in all i would surely recommend this place to everyone who wants to visit valencia.
