We enjoyed our 4 night stay here. Room was very clean and quite. Love that we were able to open the window! All the staff were very lovely. They have a great filtered water machine in the hallway. My only complaint would be the hallways and lobby have maybe a lil too much fragrance/air freshener, but luckily the rooms are not this way at all. I would definitely stay again.
