Top-floor Beacon Hill condo with its own roof deck asks under $900,000

The 920-square-foot Unit 4 on the fourth floor of 18 Garden Street in Beacon Hill includes two bedrooms and one bathroom.

It also comes with a renovated kitchen and its own roof deck reached via a loft level. There is plenty of exposed brick and hardwood too.

The scope of the place as well as its location smack-dab amid one of Boston’s more historic and more walkable neighborhoods means that Unit 4 does not come cheap: It’s asking $890,000, or $967 a square foot, through Coldwell Banker’s Petrone-Hunter Realty Group.

That is well above what the averages were for Boston condos heading into December. But, again, it’s Beacon Hill.
