I have no words to describe the place. It's perfect! I give it 5/5 review. The location is perfect, it's just few steps away from the train station, if you take airport bus (A21) drop-off is right in front of the building. Comfort building is fairly old but Sam's place (Airy Stay) is really nice, clean, and safe. Plus, Sam is really helpful in giving tips and directions. I didn't get a chance to meet him but he kept checking how we're doing and if there's anything we need. I also appreciate him for allowing us to stay longer since our flight is not 7pm. We stayed as late as 2:30pm. Thank you again. :)
