Here's the quick version:
Basic hotel, no frills, fantastic bar, close to Central Market

Here's the lengthy version:
My friend and I were in Chiang Mai, Thailand, preparing to make our way to Bangkok for a week. At the last minute, we decided to detour through Cambodia first (we had been subject to some fantastical horror stories of Bangkok in the past few days regarding the flooding situation, but decided to pretend to take them seriously, as an excuse to make a spontaneous jaunt to Cambodia). We found Lebiz on TripAdvisor, and were lured in by the idea of a library! We arrived at Lebiz at night after a ludicrously long bus ride from Siem Reap - we got it into our heads that it would be a good idea to take the bus instead of a flight. A trip that we imagined would take 5 hours took over 8, along what I now lovingly call the Cambodian Route 66 - essentially a 2-lane dirt road with a varying density of holes and livestock. Needless to say, we arrived exhausted (what is it about long rides that drains you?). But we were rewarded with a hodge-podge meal curated from the food carts and bakery a block away. I never really "got" avocado shakes until that night.

First impressions of the hotel: Really bare-bones (no room service, and a beverage refrigerator in the lobby instead of room mini-bar). They seemed to be going for this modern minimal urban industrial look with cement floors (even in the room!), neon lighting, wall-sized art painted directly onto the wall, and really sparse furnishings (one chair, barely a desk that was really a ledge along the wall that also held the television). The beds were sized somewhere between a twin and full. We couldn't figure out the air-conditioning, but it was tolerable. Our room's window was right behind the neon Lebiz sign in front of the hotel, which was a little irritating, but not so awful that we bothered to ask for a room change. To avoid this, you can ask for a room on a higher floor (we were on the first floor of rooms).

Hotel dining gets its own section, even though this, too, was fairly minimal. Breakfast was included in our stay. There was a tiny buffet with fruit and pastries, and a breakfast entree you could select from a list of about 7. While the buffet was indeed tiny, the pastries were delicious! And the hotel had homemade jams and spreads. While we were there, we got to try a watermelon jam and a pumpkin ginger jam. Both were excellent! The bar turned out to be my favourite part of the hotel! We plopped down for a quick drink at the start of happy hour one day, and ended up staying the whole time and beyond. The first drink I ordered was literally the best thing I had ever had, so I just had 2 more, while my friend was the adventurous drinker of the day and tried 4 different things. They literally spooned either half or a whole fresh passion fruit (can't remember anymore) into each of my drinks, along with gin, mint, and basil. It was so fresh and delicious. I still think about it now, 4 months later. I now refer to it as the best drink of my life. But wait, it gets better. At regular price, their drinks are only $3. So at 50% off, I felt like we were getting the best bargain in the world.

My friend and I were about a week and a half into our Great Asian Adventure and were tired, especially coming from Siem Reap and touring Angkor Wat two days before. We spent the bulk of our time in the hotel room to recharge. We did a little bit of wandering, but went no further than a few blocks away (basically the Central Market). We developed this routine - wander outside to acquire food, bring it back to our room and eat while watching subtitled American movies. It sounds ridiculous that we traveled so far to do what we could have done in our own living rooms, but it was perfect.

All in all, while it was not the great Cambodian cultural adventure that you might read about in travel books, it was Our great Cambodian adventure, and the Lebiz helped make it comfortable and boozy.
