My stay at CM Blue House was great. The little garden (with bar and eating area) in the center is gorgeous and gives the guest house a really nice atmosphere. It's centrally located, so you can reach temples etc easily and there are lots of cafes and bars close by.
Rooms have everything needed: bed, desk & chair, wardrobe, fan (a/c optional), separate toilet, sink & shower. My room was large & clean, except for the bed-cover, which looked like it could use a wash. I paid 350 bath with fan (no a/c needed in December).
The French owners were great; very relaxed, super friendly and very helpful. They organized an express laundry for me (which I needed after coming back from trekking and about to leave the next morning) and transfer to the airport at 5.30am, as well as giving great advice for massage and food places. Safe storage available.
I'd definitely stay at CM Blue House again.
