Charles was a very welcoming host & the house is extremely convenient for meetings at Harvard (I was at HKS). Lots of restaurants nearby & Charles recommended a good Indian spot just up the street upon my arrival. They had a mini-fridge stocked with water and offered usage of the Keurig in the kitchen. Also super convenient for morning runs along the Charles River. It is a shared space, of course, so I had to walk upstairs to use the bathroom, which I split with one other guest. Exactly as advertised, but be aware of that before booking in case it's a deal-breaker for you.
I'd definitely stay with Charles again!
