AC Som is good hotel. It's very close from the Metro station in Line 8, I forget the name of the staion. but you can find the station name by googling. .Even though it's not located at the downtown. than't why it's quiet. Carrefour is very close, so you can shop fresh fruits and drinks there. I recommend you include breakfast when you make a reservatiion to stay in this hotel, because breakfast is quite good, it's not fancy though. Airport is close. It takes about 30~40 minutes by bus. You don't have to transfer. You just get to the departure terminal. I recommend when you go back to the airport, you take the bus.
