U: Hi, I am looking for a hotel in the east of Cambridge with a 4 star rating.

S: I don't have any hotels that are 4 star in that area but I do have some guesthouses. Would you be interested in taking a look at any of them?

U: Yeah, is there one in the moderate price range and includes wifi?

S: a and b guest house is located in 124 tenison road

U: Can you check to see if there are any reviews that mention the rooms being relaxing and peaceful?
S: According to the reviews I have on hand for that location, the opinions are mixed.  Half found it very quiet and half found it a bit noisy,
