Suvarnabhumi Airport/Bang Na Racha Thewa|2.56km from Suvarnabhumi AirportIf you need a hotel near the airport the location is perfect. As soon as you check into your room you'l see earplugs which are necessary as you'll hear planes overnight all the time. A 7-11 is near the entrance.
I arrived at 11am but check in wasn't until 2. The staff was friendly with providing drinks and the Wi-Fi password. They ultimately let me check in about 1:20 pm.
There is a bar/restaurant on the 4th floor called Sky Bar that opens at 6 pm. The view isn't great but OK food and a place to get a beer.
The breakfast is on the 4th floor and has something for everyone. The omelette was perfectly prepared. Cereal and crossisants also available as well as Asian choices.
The staff attitude was friendly throughout the property.
The only real problem I had was with the water pressure in my bathroom. The shower and bathtub basically had no pressure. It took forever to get ready. There are two buildings here. I stayed in the one opposite the lobby with Sky Bar. My friend stayed in the main building and had good water pressure. Perhaps it is better to ask to stay in the main building.
