The "Inn at Longwood medical" is a 3-5 min walk from Dana Farber
Fenway Residence Inn is just a 10 minute walk. There's a hotel right next to Dana-Farber but I have not stayed there. There's a Marriott on Webster St in Brookline. Fast Uber trip but too long to walk. Clean with a parking garage attached. Expect to pay around $50/day to park at any hotel in the city. I've been taking my child to Dana-Farber Jimmy Fund Clinic for 13 years. Good luck - you're getting the best in the world!
