Stay away
Found hotel room door wide open. Power went out . Broken A/C. Bloody bandaid in shower. Moldy shower curtain. Blood on sheets. One bed had oil stains on sheets. Carpet so filthy that bottom of white socks turned black.

Just Meh
We needed a room for one night. Since we booked late the cost was a bit high. The room had recently been remodeled (new carpet, bathroom, vanity) so the room smelled brand new. The bed was ok as far as comfort. We didn't use the pool but it was right outside our door-it was small but clean and would serve the purpose of cooling off. Unfortunately the neighborhood was less than desirable and surrounded by car dealerships, small auto shops, etc. Restaurants could be found by driving a short distance. I'm not sure if there was a continental breakfast available. Therected was a working ice machine available and a washer/dryer located outside near the stairwell (we didn't use, so I'm not sure how well either worked). That being said - the room was very clean although with the high price I should've researched more and tried to find a better hotel that offerred a hot breakfast and a few more amenities in a not so sketchy neighborhood.(The following morning I witnessed 2 different events of yelling by patrons on both sides of our room - if my husband wasn't there I wouldn't have felt safe)

A good night's sleep.
Typical urban location. The management was courteous as well as the staff. "Breakfast" unfortunately consisted of only sugary options so we didnt partake.

Will NOT be a return customer
The room was EXTREMELY dated. The dresser was missing most of the drawer pulls so you could not open the drawers, the toilet was dirty, there was water damage around the tub, there were big un-repaired sections in the ceiling and walls, there was no alarm clock or any plugs next to the bedside for phone charging and there was an odd odor to the room. Also, there was no DO NOT DISTURB sign, so we asked that one of the days that the room not be serviced. It was not, but someone still entered the room and turned off the AC unit. So when we returned a couple hours later the room was very HOT! The ice machine is outside, and it is not completely covered from the elements. You can see in to where the ice is, and there was bird feces right near where the opening was to the ice compartment, not to mention bugs.

Don't EVER give a guest's room to someone else.
HUGE NEGATIVE - We got back to the hotel at 10:00 PM after a day of work - a 13 hour day! - to find that one of our two rooms had been given to someone else!! "But you turned in your key." We did not! I don't know who was more startled/upset - us for having someone else in the room that was supposed to be ours - or the gentleman who answered the door! The one plus was that one of the managers was right there and got us another room immediately. But this should NEVER HAPPEN to any guest. Additionally - the breakfast is abyssmal. It is nothing but carbohydrates - horrible for a diabetic. And we were told that it would start at 6:00 AM on Saturday and it wasn't open at 6:30 and on Sunday it wasn't open by 7:00. Air conditioners are very, very noisy and the switches are unreliable. One of our two rooms never got below 80 degrees on the first night because the switch didn't work right. Bad night's sleep!!
