    "My stay in an all-female room with four beds was comfortable. The room was clean and spacious. The noise from the street was a bit much, especially the neighborhood dog that barked at different hours of the night (should have brought my ear plugs).

    "Super tiny room with only one exit from the bed so my husband had to crawl over me to use the bathroom in the middle of the night. Barely any room to move around in the room. Felt like we were in an overnight train car. The TV also didn’t work we couldn’t connect our Netflix to it no matter what we did. Nice lobby and easy check in. Only stayed 2 nights but the staff were great."
