We booked the Pathumwan Princess Hotel in Siam via agoda.com. What made us choose the place is the great hotel service review and its proximity to the shopping complexes and the skytrain (BTS).
From the Suvarnabhumi airport, we traveled 45mins to the hotel and was greeted by a chic and clean reception area (2nd floor). The front desk folks were warm and very helpful. It took us an extra effort to adjust to their accent, though. They knew English but it wasn't that easy to understand. Hand gestures and nods were essential to foreigners in Bangkok.
We took Pathumwan Princess' ExecuPlus Suite. It had a spacious receiving area and an adjoining bedroom. Upon entering room 1215, we were delighted to get a whiff of the room's relaxing cedar scent! The room's furniture and interior was worth the price tag.
