The apartment is beautiful and Jason is an awesome host.
We staid with our two kids, my parents, and a cousin and had plenty of room! The trundle bed was perfect for the kids and playing foosball was the highlight of their trip.
The kitchen is great, with all the things you need to cook and plenty of cabinet space if you have food to put away.
Jason sent us great information for the apartment in advance. We were able to show up and settle in with no difficulties. We had a wide range of needs and the apartment met all of them. Also, the neighborhood is super fun with shops, groceries, and easy walk to Boston Commons (that has a huge playground) and the Public Garden.
