i started with the budget room on the 4th floor. at the end of my trip i moved into the nicer room on the 8th floor. i dont think the room are amazingly bigger, but they are laid out much more efficiently. being that high up, you can get much better sleep as you cant hear the street level noises. you can still hear honking cars, but they are much less pronounced. not shaded by the next building, the sun does shine in strong. you will need the AC on when you are inside. the room gets really warm if you are out all day. i think the fridge turns off when you are out of the room? either that, or the room is so hot, it cant keep up. it isnt a compressor style fridge, more like a peltier heat pump style. no noises. so, you can take it with as you think. good for drinks, but not for long term food. i am still deciding on which room to pick next time, the room was nicer, but i am not sure if it was worth the extra money. i am the type of person who might prefer to spend it on extra food or gifts on the trip. i do know the 4th room floor rooms (single bed style) are all different. i have been in 3 and they all have different layouts. this last trip i was here, i found the bus that goes to the airport. when you exit the hotel, and turn right, there is a bus stop may be 3 minutes walk. you need to take bus #334 and it will go all the way to the subway station. it only takes 2 rmb each ride on the bus, and you can use the subway prepaid card. you then take subway 1 more exit and take the airport shuttle. much cheaper then taking taxi for 80-150rmb... the bus isnt frequent, but it goes go by. there is no sign on the bus stop that it goes there. if you are looking for a place to go, try taking the same bus the opposite direction. it will take you to a mountain at the end of the line. i think the whole transit from mountain to subway is only like 40 minutes? very useful to know. going to the mountain, there are places to stop and eat on the bus line.
