Location right by Colosseum is amazing. Triple room had really nice views, facing a park and overlooking an archeological area. You could see part of Colosseum if you stuck your head out of the window. Only 3 of 5 rooms have views. The cons of room w/views is that it was noisy. Street below is full of late-night bars (open til 2am) and there are several busy roads intersecting outside. The windows are good at keeping noise out, but light sleepers like me may want earplugs.
The triple room was large, clean, and nicely remodeled, but light on amenities: no tea/coffee, no complimentary water, no robes/slippers, and really slow WiFi. There were however plenty of towels, soap, shampoo and even some toothbrushes. There was a tiny safe in the room (not laptop sized) and a mini-fridge. All the rooms are located on 2nd floor and there is no elevator. Dragging heavy luggage up the steep, narrow stairs is painful. 24h front desk is very helpful for late flight arrival. We did receive a confusing message saying there was no 24h reception and late check-in would incur additional cost; neither turned out to be true. Ring Imperial Rooms if front door is closed.
The biggest issue we had was a really bad sewage smell in the bathroom. Thankfully it stayed in bathroom so bedroom ok. We mentioned it on 1st morning and upon return everything smelled fine. Unfortunately, by next morning the smell was back. Hopefully it is something they can fix. Other guests weren’t having issues.
