Thoroughly enjoyed my stay at the Ulaanbaatar Hotel. The position is great - very close to the central square, history museum and art gallery. It's an older Soviet era hotel which has been refurbished, and has a few quirks like rather uneven floors and (in my room) a shower that tended to spill water over the bathroom floor, but was otherwise roomy, well equipped and very comfortable. Nice buffet breakfast, and very helpful staff. It's also excellent value by international standards. Definitely recommended.
