Liked: Cleanliness, staff & service, amenities, property conditions & facilities
A lot of people told me not to rent here. And I decided to rent a room for one night. And let me tell you those people were wrong. I loved the room. I loved the staff. I loved the quietness. I love the privacy. It’s an amazing place I highly recommend this place. Don’t always believe what you hear. Go see it for yourself. The owner is a little straight, but he has to be because people intend to take advantage. So rent here for a peaceful pleasent stay.

Disliked: Cleanliness, staff & service, amenities, property conditions & facilities
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!!
