We arrived to Siem Reap late in the night, didnt do any reservation of accommodation beforehands therefore we took the first offer from local guide which was the Green Banana Guesthouse - which was obviously a mistake.
We paid 15 dollars for a double room with AC and bathroom (and non-functioning TV). The room was quite horrible including mould, ugly smelling bedsheets and thin towels (also smelly) plus one additional centipede crawling around the room.
The staff was quite friendly, but offered us the worst possible exchange rate when we wanted to change dollars (luckily there were many other possibilities to change money in the neighbourhood) and also too expensive offer of a tuk-tuk driver for the 3 days visit of Angkor area (better price was from tuk-tuk drivers on the street).
The guesthouse has a restaurant too, but not a very good one.
Ah yeah - in the leaflet the guesthouse is promising a pool. Yes, there was a pool located near the restaurant, but you can swim there only if you like mould, dark green dirty water and fish swimming with you! I think nobody swam in that pool for a half of century.
In general, the leaflet of the guesthouse with the nice pictures looked very much different from the reality of this guesthouse!!
