Reasonably good, but certainly not spectacular
The staff were excellent - Josh on Reception was particularly helpful. And the location just outside Kenmore station was great for access to Boston's sights via the Green Line. But I found the bed - in particular the pillows - lacked support. And the decor in our room was very dated - and the shower over the bath was little more than a dribble. I'm really surprised this is ranked #1 in Boston, if I'm honest.
