The rooms were new, clean and quiet. Very helpful staff and they speak English. Very close to the city of science but not that close to the city center. It has wifi, buffet breakfast and room service but we did not check any of these.

The hotel is a little far from the center, but a 5 minute walk from the Ciudad de las Artes y las Ciencias. Amazing. Loved Valencia, loved the hotel. There's a bus right across the street that takes you to the center, and takes about 20 minutes. The rooms were good, the staff was friendly. Overall, a great value. Would go back.

Wow. The NH Las Artes II was the NH Las Artes Express and in changing its name, it attempts to get a fresh start- or does it? I booked this hotel knowing that it was not the NH Las Artes as I had business nearby at the Palau. It is close, but is a very cheap, discount version of what NH Hotels do. To be honest, it is not the material cheapness, the rooms with no space, bathroom smaller than the train I used from Madrid to arrive. It is the dopey service and the fact that they direct you to their bigger, classier bro across the street for anything that makes one feel like maybe twenty dollars more would have been worth it.
I arrived and the internet company had the wrong address but I knew I was at the cheapie. I told them about the address mistake and that the company, Cheaptickets, had the wrong address. Tripadvisor doesn't have the right name at this point. The tall statuesque employee told me " Well the address doesn't matter because you are here.". In other words, they actually do not care that there is misinformation out there about their property because they benefit by doing nothing. EEK.
I tried to dine in the NH Las Artes and that wa a joke as they had to tell me three times that I would have to pay for the breakfast which hello!, is what one would expect. I decided to ahve a coffee and they told me to go sit in the lobby and they brought out a cup of coffee without a napkin, spoon, milk or sugar. But they did bring the bill? Odd- no? The level of service at this hotel is the lowest I experienced in Spain. The NH Hotel chain should review these two properties but they must not be an efficient company as their webiste wa down for direct bookings for over two weeks in December. That is why I used a third party.
My room in the NH Las Artes II ( no longer the Express as I was told by an employee) was the cheapest room that a one star would have on he side of a road in the US. I cannot recommend it. Maps of Valencia do not show properly the proximity of other hotels. Do not rely on the few that state that this property is the only one to be close. Sometimes distance is worth it to get a better view.

The hotel is located close to the City of Arts and Science, also not far from the beach or center (10-15 min by bus to each). But to get to the Congress Center you need to change 2 busses. Room (single) is rather small but cosy and comfortable. The state of facilities is very good. There's free WiFi in the lobby.
The windows of my room were to the inner yard so it was rather quiet at night but they also have rooms with windows to the street (beware it could be noisy).
