We stayed in a double room with private bathroom at the back part of the hostel. The room was clean and basic - good shower pressure and hot water. We were able to get a weak wifi connection in the room, but it was much stronger in the communal areas.
The hostel is located past the centre of town opposite the seafront. There is a restaurant on site which provides reasonable food at a reasonable price (they provide room service for rooms at the back of the hostel - just pick up the phone!). We were staying on a Sunday & the restaurants in the town closed early, so we did eat dinner at the restaurant & breakfast one morning (it is not included in the price). They also sell water, soft drinks, beer & wine.
The lady at reception spoke English & was really helpful with providing information on the local buses (they leave very close to the hostel & are very frequent), as well as how to visit Huaca del Luna and Chan Chan without a tour (it really is easy & much cheaper). She also arranged our bus tickets to Ecuador, which were delivered to the hostel, saving us needing to go to the bus station. We also used their laundry service, which was quick and cheap.
If you are looking to stay in Trujillo, do look at staying in Huanchaco - it is a laid back fishing village within 20 minutes of the city.
