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!!

We arrived and was informed that they had no rooms available left. The lady at the front desk was very nice and was trying her best to accommodate but we ended up getting a room after all that they had some kind of hold on it. We went to go eat next door and once back turned the AC on and nothing happened, the AC unit was loud and would blow very low air and kept on having an error message come up OP was the message. We were honestly very tired and kning they had no other rooms decided not to say anything and just go to sleep. It was hot but not to the point of being unbearable, having AC would have been nice though. We took a shower in the AM before we left and noticed the tub was clean but very stained and so the appearance was dirty. I was thankful for the lady’s tenacity to look to accommodate my wife and I but honestly wondered if they knew that the AC did not work. I reported the issue in the AM before leaving and was told “sorry, I’ll report it to maintenance” I honestly would not stay here ever again.
