This room is pretty much exactly as it seems. It's a private room, with a comfy bed and a private bathroom. It's not a frilly, luxury stay, but, then again, if it was it'd be more expensive. The room was clean, it's only a 15 minute walk to the convention center and it takes only a few minutes to get to the restaurants and bars on Broadway (Shenanigan's is awesome, btw!). It was a perfect setup for me and my wife.
Here are some hopefully helpful points to know before you go:
It is a bit of a hump to the Broadway T station. Not impossible; but not really close. Be prepared.
There are some absolutely beautiful churches in South Boston that are well worth taking some time to see (at least one of them is an apartment complex now).
If there are people upstairs, you will hear their footsteps, their showers and the toilet flush. Just expect it.
If people are coming or going, you will hear them at the door and using the stairs.
There is a kitchen and washer/dryer downstairs (which was particularly handy as it rained almost every day).
On a (very) personal note, if you need to poo, open the window in the bathroom and keep the door closed until it airs out. Otherwise, it will overtake the room. Trust me.
Dan was a great host! He was always in contact when I needed him. Whether you're in town for a convention or for vacation, I would definitely recommend his room!
