High-class 24-room independent boutique hotel in the Blackstone Comprehensive Music Park. M+, which references something about "music," has been described as lovingly hand-crafted for the hundreds of foreign musicians that the SSO brings in every year. The interior's very nice: loving tributes to Art Deco stylings and the Blackstone Apartments themselves, each floor sporting its own tile mosaic pattern, without being gaudy. The rooms are about the size of the historic apartments. Homey and urbane. We're told that the conductor of the SSO is already a huge fan.
