$55 a night, BUT you can leave your car at the hotel until 4pm the next day even if you check out in the morning.
$55 for the night
There is a lot across the street from the main entrance. I just paid $44 for 24 hours.
Valet is $32 for up to three hours or $52 per day for guests. There are multiple parking garages for Massachusetts General Hospital in the area with more reasonable rates.
