The "Smiley" was my home for 7 days while I waited for a Thai visa back in 2011. I felt like a king, having this big double bed, TV and aircon for 10 USD at the time. I was in a third floor, right in the corner, with windows looking everywhere. My bed was made two times per day, the mattress was terrific, and I just spend the days watching cable TV and walking around town while my papers where getting in order. Why to spend your money and time in a filthy hostel/guest-house when you can do it with style? Yes, it is not close to the river, but you know what? This place made my stay in Phnom Phen (not the best city in SEA) completely bearable.
