You want to book this place. Now. Seriously, it's great.
The neighborhood (jamaica plain) is very safe, quiet but full of options for eating out and such. The apartment is ~5 minutes from the metro, which makes getting around really easy. Also, Samuel Adams Brewery is less than a mile away.
Kelly and Phil were awesome hosts; they are super kind, made sure we had anything we needed, gave us suggestions of places to visit, running routes, etc.
Last but certainly not least, the apartment is awesome. It's pretty, comfortable (oh, that king size bed!) and well equipped. Seriously, you want to stay here.
