Nicolo's place was amazing. It had so much character and charm, and if you really want to immerse yourself in a historic visit, you have to stay here. Plus, Charlestown is very cute and charming and in a great location. It's just minutes from the Freedom Trail and directly over the bridge from the North End. Downtown Boston was only a 10-minute walk, which was great. We only took a Lyft to/from Fenway, but you could easily get there by subway (also a 10-minute walk).
Nicolo was very responsive and added so many nice touches to the house. Do note that if you're looking for something very modern, this is not the place. It is an older home (built in the 18th century!), so the floorboards are a little creaky and the bathrooms are small. But honestly I'm so glad we stayed in this home. It just added to the Boston experience.
