Julio is a fantastic host of a wonderful apartment. He was very engaging and communicative from the beginning and replied to any messages instantly.
His apartment is on the top floor so there are some steps to climb but it's definitely worth it for the light and airy space as well as pretty street views at the top.
The appretment is clean, well equipped and there is a great supermarket on the next street only a few steps away!
It is a ten minute walk from the old city and cathedral where there is a brilliant night life and incredible restarants and bars, lots of beautiful shops in the day time, and plenty of ice cream stores if your not full from your exploration of the central market located there.
The magnificent train station is not even 5 minutes walk away and again there are great places to eat and drink, shop and site see just a stones throw away. I would also recommend popping into the information hub on the street opposite the train station near the fountain, as they supply you with a wonderful map of the whole city and beach, and it is a great way to plan what you want to do on your trip!
The science and art buildings are a must to visit and are located on a beautiful strip of nurtured parkland once a dryed up river next to the city. They are maybe a half hour to 45 minute walk away from Julios apartment. And if you have made it that far, then the beach isn't too much further, with its lovely clean sand and a number of seaside cafes and restaurants to choose from. But you might want to get the tram back to an underground after, which will bring you out right by Julios apartment, as the beach is a fair walk away.
I would definitely recommend Julios apartment if you find yourself visiting Valencia. It's central to everything, is very comfortable and clean to stay in and has everything you need for a great trip!
