Call for reliable Tuk Tuk service: +855 92566695 Mr. Deth, he is very reliable and speaks English. However arriving at airport I recommend to take a taxi for USD 10-14, much more covenient than eating dust in tuk tuk for 45 minutes. Within city just use a tuk-tuk, pay for a whole day (USD 10-15) or per trip.
I love these smaller boutique style hotels: Blue Lime, with a small pool and rooms in type of townhouse are very nice (50USD) or Hotel 240, no pool, but great location in street 240 and they operate an organic cafe, and you can use pool from other sister hotels like Blue Lime or Plantation. The Mango madness is just great in that organic cafe. Also visit The Mansion Hotel just for an espresso. Wonderfully restored townhouse.
Cafe’s: Java Cafe, great breakfasts and sit outside on first floor overlooking Monument square, any Browns Cafe for good service and free WiFi, Le Shop Cafe in street 240 has the best croissants.
Restaurants: K’Nay – must go here for cocktails and great honest food. It’s gay owned and really low key and wonderful service. Bit difficult to find and have added a little map. It’s a little alley next to Street 19 entry from Monument Sq. Walk from Street 240 is 10 minutes.
Other restaurants: go to “Friends” (just of street 178) or Romdeng (also from Friends organisation). These are non-profit restaurants and service as vocational training centres for former street kids.
Spa: Bodia (178 street) or Bliss (street 240).
City: visit S21 (the prison in which Khmer Rouge tortured 20,000 people) and Killing Fields (half day trip, do not go in Tuk Tuk (crazy dusty road), but take a car and do take the guided recorded guide thing, take 2 hours to really let it sink in) Make sure to have a stiff couple of drinks after all of this, cause you’ll need it.
Nice to watch (but no prob if you miss it): Royal Palace, Wat Phnom, National Museum, Russian Market, central Market.
