Been to this Wat numerous times during my 10 day stay at Phnom Penh (and still here waiting for New Year to come along). It's fortunate for me, that by chance, my guesthouse is very close to this Wat, probably a 3 minutes walk.
Love everything about Buddhism, so this Wat is ideal for me. Friendly Monks, always willing to speak English; great ground staff. This Wat is made up of 44 buildings, all housed within it's own perimeter wall - access is via 3 open gates and it's free of charge.
Some great buildings and many areas to sit and chill out, watching the Monks go about their business. If you read this before you go, please be respectful towards this Wat (and any other for that matter). The "look at me, my shorts are so short thay are up my bottom" and the "it's too hot to wear anything but a vest top" looks are pretty much crass when it comes to religious areas in any country.
