sophiegirl, if you're going to be near the Hop, it's Johns Hopkins. That was the man's name afterall.

sophiegirl mentioned the main campus which is Homewood, not the hospital in East Baltimore. There is the Cross Keys Inn in Roland Park which is a 7 minute drive from Homewood; that's where we stayed in April. It's a 3* Radisson property now but it's been there for decades. Across the street from the Hop is the Colonnade but it is overpriced. You can priceline a hotel near Homewood easily. It's the region called "University".
