From 93: Take the Government Center exit (toward Faneuil Hall/Financial Dist/Aquarium). Turn left onto Surface Rd/John F Fitzgerald Surface Rd. Turn right onto State St. Turn Right onto Merchants Row. 21 Merchants Row is on your right.
Boston Medical Aesthetics is only minutes from the Government Center, State Street, and Haymarket T stops.
Limited metered parking is available on the street, but is becoming more challenging. 60 State Street Garage is located directly across the street. A good option is Haymarket Center Garage (also called Parcel 7), which is very close by. It is located at 136 Blackstone St., above the Boston Public Market. You can park there for up to 3 hours for $3.00. You simply have to validate your ticket. To do so you need to make a minimal purchase from Adam's Pizza & Convenience Store, located across the street from where you exit the parking garage.
