Solidifying the buzz around Tbilisi as an emerging travel destination is the Stamba Hotel, which opened earlier this summer in a Soviet-era publishing house, and features a glass-bottomed rooftop pool, on-site chocolatier and an elegant casino, all set around a five-story atrium. More than 80,000 books—scattered throughout the hotel, as design elements and for actual reading—pay homage to the Stamba’s history. —Abigail Abrams
