7.8/10 Good! (1,002 reviews)

This is an older hotel, definitely strange smells throughout, worn furniture. The bed was clean but sheets had a couple of old stains. All the staff were kind and helpful. Definitely needs a makeover for a more comfortable stay, but was okay for one night last minute booking.
