This apartment was generally fine. If you have a bigger group and want an awesome location and have a car to park this place would be good. The apartment is on a quiet block/area. The floors and surfaces were really clean as well.
Pros
Location - really great close to everything can walk to most places in Boston from here beacon hill, back bay, downtown crossing, seaport etc
Free parking - there is a spot that is in a garage around the corner so you save 35-60 a night (parking garages in the area)
Space - there are four truly separate bedrooms which is unusual in the city proper
Layout - there is an actual dining table and full kitchen - 3 bedrooms in the lower level with the one bathroom and one king bedroom upstairs off living room. Also three TVs one in kitchen, living room and one in one downstairs bedroom
Host communication - super responsive host - one of the fastest to answer questions ever
Cons-
Pricing - If you click around on availability the pricing changes drastically and paying 2k a night to stay there would be absurd
Mustiness - it might have just been summer and unoccupied for a while but upon opening the door to the unit there was a big smell had to turn on all window units etc
Steep stairs - if you have any kind of mobility issue this is not a good spot for you - the stairs up to the front door are steep and the stairs inside the unit are equally steep and narrow
Overall if you can get the right price, have a group care about location and parking it makes sense. The space has been minimally updated over the last 20 years which may or may not matter to you. That being said the unit was clean!
