I stayed at Gosia's house for 5 weeks while I was working at Harvard, and it was perfect. Gosia's house is quiet and peaceful and in a beautiful neighbourhood - quiet, safe, with lovely parks & running tracks nearby, and a supermarket & other shops easy walking distance. It was easy to reach Harvard Square by frequent & fast buses which connect with the Red Line T if you need to go into Boston.
The house is very comfortable, and Gosia is an experienced and thoughtful host. There was everything I needed in my room, and in the shared kitchen. And for long stays, there's an easy to use washing machine & dryer, which was so convenient.
Gosia is a lovely host - excellent & friendly communications in booking, and it's clear she enjoys hosting. I could interact as much as I liked or hide away to work if I needed to. The added bonus is that there's always someone interesting in the house!
Thanks for a lovely stay, and I'll be back!
