A reliably comfortable stay at Route Inn
My husband liked it, and this was our second stay due to other commitments. This time we couldn’t book a single room and stayed in a twin, but he said it was spacious and he was satisfied. The large public bath is also spacious, and he really likes this Route Inn. Thank you very much for your hospitality.
