6 people flew into Cambridge from all across the country (and one from out of the country!) for a friends wedding. We booked Zazy and George's place largely because it had enough beds and had the appropriate location. What we got was a super clean, very welcoming space with comfortable beds and fantastic, flexible hosts.
We all flew in and out at different times one arriving early and another very late. Our departure was similar. Zazy was very flexible on both ends of our stay. We once locked ourselves out and she was there in minutes.
As far as the actual place is concerned it was extremely clean and the pictures and description was very accurate. I'd highly recommend the place for your next large group needs!
