Alicia's space is great and in an ideal location...a little over a block from Prudential Center or Copley Square T-stops and in the beautiful Back Bay neighborhood.
My husband and I had an amazing time. The space was clean, bed was comfortable, but the location really sells this unit. We didn't end up staying there much because there's too much to do around the city.
Only minor suggestion would be to get heavier / darker outer curtains for the summertime. The sun comes up so early that we were awake by 4:30 to 5:00 every morning. We didn't mind too much as we're early risers in general...but might be nice to be able to draw the curtains and get a little more rest :)
Would highly recommend this rental to anyone who wants to see Boston.
