Jonathan's spot is exactly what you see when you're looking at the listing. You'll have your own room in this large brownstone, with great lighting and all you'll need to feel comfortable after you have spent the day traipsing around Boston. While I only spent 40-some hours in Boston, this place was better than I thought it was going to be as it pertains to getting around on public transit. This was my first time in Boston and I had no concept of anything Boston-related... this brownstone was an 8 minute walk from the Orange Line, which is ~15-20 minute ride into downtown; 20 minute walk+ride to the Sam Adams Brewery in Jamaica Plain; 3 minute walk to a bus that'll take you to the Emerald Necklace. It was nice to be located in a place that had a number of transit options to supplement getting around on foot.
Jonathan is extremely responsive, attentive to detail, and wants to make sure your stay is great. One thing to remember, write in the guest book!
