They are in the process of some renovations but no problem with noise or inconvenience. Staff was very nice and helpful. They do need to improve the breakfast which is very limited.

Very convenient location in the city. Can be a little bit noisy but that’s to be expected in the city. Just the occasional emergency vehicle sirens. Room was clean other than the hair I found in the bathroom. Staff was very friendly and accommodating.
