Mixed experience
The property is quite tired. I had to move room because of a problem with broken fittings.
Thankfully the staff upgraded my room, which was better.
I'm not sure I'd stay again.

The hotel is located in an amazing and safe area. Unfortunately the check in process is not great. The room is small as expected but you could barely get into the bathroom with how the toilet is placed and the door doesn't swing open all the way. The floor in the bathroom was dirty, the shower drain had hair in it, the ceiling vent had dust on it that flew down when you turned it on and the bathroom vanity cabinet was broken and beat up. The room space is decent, but the bedding is really bad. It's a synthetic fiber comforter that has been washed so much that the fibers just clump into certain areas and should be thrown out. Definitely not what I expected.

A wonderful place for singles or couples. Not a great place for families because the rooms are small due to the premium location. However the hotel is excellent if you're going alone or just with another friend. I can't recommend it enough. The rooms are small but that's because of the lower price for the absolute top tier area it's in

The room was well kept and the toiletries were complete. The shower space is a little too small though but there was a lot of shampoo, conditioner and shower gel available. The dispenser pump of the shampoo was defective though. The staff were accommodating and quickly responded to requests for assistance such as cleaning arrangements. The online check-in and check-out experience was seamless and convenient. Generally, our experience was quite good.

I liked the location, I liked my room, the bed was great and so were the pillows. The shower experience was 5 star. However, not so clean! Hair here and there, the place could use a good wipe down! I wasn't there long so it wasn't much of any issue. It's as if the hired cleaners have not been trained how to properly clean a room. Also, the room is stuffy. AC resolved the problem for me, and it was 45 degrees outside and raining. It would probably be terrible if one needed the heater instead of the AC.

Room code didn't work right after check in, I had to go back down to front desk and wait for the code to be assigned again. Shower gadgets were poorly maintained and hot water takes too long, also cools down after a bit. Staff friendly and helpful.
