4/10 Fair

Water in toilet kept running. Room was ready for check-in and would charge to get in early. Tiny room with no space for luggage or a closet!

8/10 Very good

Fairly small room in excellent location. Clean, everything worked well. Very friendly and helpful staff. Faast, reliable wifi. Checkin via app is a little complicated, bunk beds in room have comfortable mattress but seem confining. TV has no local or cable channels, just your streaming services.

Tiny Room
We booked a room with 4 bunk beds. When we got there it was so tiny that we could only open one suitcase at a time. No television, chair or fridge and limited towels. We had to ask to get more and to get them changed out as we were there for 5 days and there is no cleaning staff there. Also the elevator did not work for 3 days and we were on the 6 th floor. The room was clean but it is not made for adults. The hotel is not in the best area but it has a passcode on the main door so we did feel pretty safe.

8/10 Very good

The location was central and the staff were very nice. The room was clean. Biggest problem was no window in the tiny room. There was a window but it looked out into the hallway. Also it wasn't made clear to us that there was a lounge on the second floor so we never knew about it until the last day of our 9 day stay! Knowing about the ice machine, microwave, free coffee, and laundry room would have made all the difference to our stay. Apparently it was in the check in instructions but I never saw it despite reading them.

Great place our room was just loud from heater/ac
The hotel is great. Extra clean and very comfy. GReat price, perfect styling. No fuss. I would give 5 stars and top ratings if our room ac/heater was not making loud crazy sounds all night as well as loud plumbing sounds in two walls. We did not sleep. Room 705 needs some attention.
