Cigarette smoke was all over the place from guests next to you and across from you to its own restaurant and staff. I couldn't stand the smoke so we just forfeited our prepaid room for 7 nights and booked another hotel the very next day.
Also, the shower and toilet are not separate. You can literally be taking a shower and doing your business at the same time. :) But this is standard in most Thai bathrooms, except for those who have adopted the American standard. The hotel we moved to has a separate shower. The best part is that this hotel is just $5 more a night, but with a difference like night and day!
