The first room we got was off. The a/c didn’t work and a couple of items were outdated. However the person at the front counter gave us another room and turned out perfect. Great location, clean and all the amenities you need. Great room, location and customer service.

Don’t bring a family here

Very uncomfortable atmosphere, the sheets were soggy, floor was dirty, there was mold, room was stale, paint was peeling off walls and doors. Not to mention the people who stay at this place are very questionable. I try not to jump to conclusions but I can’t deny the things I heard at night time.
