We really enjoyed staying at Paul's apartment. It was very clean and the water is hot with a good shower and very nice bath. All you could want in the kitchen area. The area was excellent - perhaps not the smartest side of Beacon Hill but a great location as easy to walk anywhere. It was a great base from which to explore Boston. Ground floor so meant no stairs to lug cases up but may be a little dark in the summer. We were there in February so it didn't matter - it was very cosy and we appreciated the extremely comfortable bed so slept extremely well.
Definitely recommend.
