The hotel staff is nice and helpful (especially the security guard is very kind), the facilities are complete, there are no missing amenities, the front office staff also helps with the check-in/check-out process.
(A little note, if guests refuse any offer, the front office staff must remain professional and friendly, don't just say "grumpy," unpleasant to look at. The front office is like the face of the hotel, so it must give a good first impression).
