U: Hello, can you recommend a moderately-priced 4-star hotel, please?

S: There are no moderately priced 4 star hotels but there are 11 guesthouses that fit that criteria.  Are guesthouses an option for you?

U: It needs to have free parking

S: The acorn guest house definitely fits your needs.  It's 4 star and free parking.  Shall I book you a room?

U: Is this hotel known for it's clean rooms?
S: The Acorn Guesthouse is pretty much always clean. I could only find one bad review in which the guest had a dirty room upon arrival, but it was cleaned quickly.
