Thinking about going for a month to Asia. Recommendations for Cambodia?

Hola Carla! You should definitely spend a couple of days in Phnom Penh, it's a great historical spot. The city reminded me of Bangkok for it's lively all the time, but it's less polluted & with a much nicer climate (=dry). The hotel we stayed at was not great so I won't recommend but we had breakfast at Oknha ChhunThe 240& lunch at Friends the Restaurant and both were delicious :) As for things to do, we enjoyed walking by the Mekong River, visit the National Museum and the terrible Tuol Sleng Genocide Museum. 

On top of that, you should definitely go to Siem Reap. I hated the city itself but the surroundings & temples are amazing. You can take a 8-hours long bus from Phnom Penh, landscapes are wonderful along the way. (Bring your scarf & coat to cope with the ice-AC bus :)) We stayed at My Home Tropical Garden Villa Siem Reap and it was cheap, clean & quite central. Approx US$20 a night. I recommend you to rent bicycle at the hotel (US$1 per day!) and organize your own trip to the temples. Temples are just amazing!!

Have fun in Cambodia!!

Hi

1 month in Asia is great. In my personal opinion ,this is the list of city to visit setting in priority, up to you to set your holidays: Siem Reap, Phnom Penh, Vientiane, Luang Prabang, Rangoon, Bangkok, Hoi An , Ho Chi Minh City.

1 month in Cambodia should allow you to see most of it. On top of the classic ( absolute must) Siem Reap, I would add Phnom Penh(capital city but very quiet, interesting on the history side, Khmer rouges), Battambang(nice town) and Sihanoukville(beach). If you are more adventurous, you can visit the north east and go for Elephants. It's not easy to reach but there are buses going there (get ready for 8hours or so on the road). Easier to reach, ou can also add Kep (old abandonned colonial houses) or go up the Bokor Hill Station(weird abandonned resort) although I would say these last 2 are less impressive than the rest. 

Happy travels
