hot water off, on took 20 mins to warm,no coffee or continental breakfast nothing! They said no break. because since covid they weren't allowed, a law. That's a lie! No such law! Tv-electronic box hanging out from under tv that was on wall. $20 cash demanded held til return of door key. electric plate turn-on light cracked & broken off by sink-shock potential! shower equip.hanging barely attatched. They had already taken our credit card and submitted the cost. Got their money and we were told there was NO refund. We paid a total of $167.54 For Crap! Good- heater worked and bed was comfortable. One more thing! To get entry door open you had to bodyslam it! We feel totally ripped-off! I'd dump them!!

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 The a/c didn’t work and a couple of items were outdated.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.
