10/10 Excellent
"Affordable with friendly staff. Our single rooms were on the smaller side, but priced so that we could each have our own instead of sharing a double. Staff were super niceand helpful. They have a really good and affordable coin-op laundry which was better than other hotels we stayed in. "
