Budget hotel within a 10 min walk of the central town square and across the road from combi buses to Chanchan and Huanchaco (1.5 sol). Showers hot, wifi good, basic breakfast (as expected), staff universally lovely. Room a little dated but provided everything needed. Very happy with my stay.

We stayed there one night, when incidentally locked out at the night from our other room (people are crazy there about security). A bonus, comparing to other places - at night the entrance is not barricaded, there is always a receptionist who needs not to be waked up. The receptionist spoke English. It is not cheap though. The room was clean, but design of lights, etc., not very optimal. Acoustics is pretty quaint, as it happens with those building, try to get a room farther from reception or on the second floor.
The hotel is not central, but close to good restaurant strip, open late in night, and in a walking distance from the central square. Near a route of many combis, so the location is convenient.
