U: Hi, I'm looking for a place to stay in the centre.

S: There are 2 guesthouses and 3 hotels in the city centre, do you prefer one or the other, or are there any amenities that you'd like?

U: Yes, I would like it to have free wifi.

S: The Alexander Bed and Breakfast is a 4 star guesthouse that is cheap.  Does that interest you?

U: Do they offer free wifi or free parking?

S: Yes to both.

U: Great. Please book it for 5 people for 5 nights starting from wednesday.

S: Unfortunately that didn't work. Do you want to shorten your trip?

U: Sure, how about two nights?

S: I was able to book that hotel for you for 2 nights.  The reference number is 8LCNFKVO.

U: Wait, can you also check if the WIFI they have is good as well?
S: The Alexander Bed and Breakfast offers free Wi-Fi to guests. Reviews from past guests say the connection is fast.
