Hi,
we stayed at the arnoma begining of oct only for 3 nights,our room was a bit dated and smelled a bit fusty,the hotel is right in the middle of plenty of shops although the nightlife is a taxi ride away, we found the hotel bar far to expensive it cost us 630thb for 2 small lagers so beware i would not recomend a this hotel to anyone there are far nicer hotels in bangkok.
