I stayed here during the San Fermin festival, so all the prices were higher than usual, I presume. Regardless, I spent €120/night for a one bedroom, and for that price I expected a lot more than what I got.
The hotel is located in Navarro, so getting to the Pamplona city center is a bit of a hassle. And there isn't much going on in Navarro, so you'll probably spend most of your time in Pamplona. My room was quite small. It only had the space for a bed and a mini desk. The bathroom was odd, as the shower didn't have walls surrounding it on all sides. On the plus side, the room had air conditioning and a closet.
Overall, I expect €120/night to go much further in terms of amenities and location regardless of the festival.
