For weeks, the estate at 1405 and 1399 Tremont St. has featured a “coming soon” sign out in front of its double-gated entrance, neighbors tell us. Now it’s ready for the taking. With two homes boasting a total of five bedrooms and eight bathrooms (four full, four half), the property features towering ceilings and stunning custom woodwork, as well as some unique features befitting the home of a famous Aerosmith guitarist: guitar emblems carved into the marble flooring of the entryway, guitar heads visible on the balcony above, and a swimming pool in the shape of (what else?) a guitar.
