We have stayed in Juan's apartment almost a week and the experience was excellent.
The location close to the beach and harbour is great, with great restaurants, bars and beach in walking distance. If you feel really lazy, literally 1 min away from the apartment is one of the best tapas restaurants of Valencia, Casa Montaña and a very cool bar, El Viento. The area is also well served with supermarkets, pharmacies and nice places for breakfast.
The area is very well served of public transports that are reliable, cheap and will take you everywhere you want to go in the city. I wouldn't advise to take the car. It's crazy to park in the neighbourhood as in almost the rest of the city.
The apartment itself is really cool. It was recently renovated, is spacious, great bathroom & kitchen and it has everything from good WiFi to hair drier.
We were welcomed by Victoria and we there are not enough words to thank the kindness and good advice she gave us. It surely made our trip better.
Highly recommended place to stay.
