We had a wonderful stay for our first trip to explore Boston! It was a 5 min walk to the orange line Roxbury Station T stop, we used the subway to get around the city with no problems (& walked a lot because once you figure it out, it's fun to navigate!). The apartment neighborhood seemed ok but we were back before dark most nights because we had our 1-year-old in tow. It's about 4-5 stops to get downtown I think, only 10-15min.
Alex was a great host and we ran into him more than once for a quick chat & he was happy to answer any questions or offer city tips. Apartment was perfect traveling with a toddler, very clean, great space with all the necessary amenities (sink, soap, dishes, full kitchen with updated appliances, sheets, towels, iron, tv, etc), bedroom/bathroom are downstairs, living room/kitchen upstairs (plus a deck!). There was room in the bedroom for a pack n' play & room upstairs for a playpen! (Bring a baby gate if you don't have a huge cooler to block the stairs like we did!)
Boston is a great city, glad we stayed here to check it out! Thanks Alex!
