Stayed at the De Arni on two ocassions, once at the beginning of my trip for 5 days and again for 3 nights at the end. Staff are really friendly, free wifi in the rooms is a plus and price was value for money considering central location.
Not a large hotel which is good thing, this means they know you and you always get a friendly greeting when you walk through the lobby. They remembered me when I checked back in at the end of my month long trip. The rooms are not huge but perfectly adequate and very comfortable. Fridge, tea/coffee facilities, electronic safe etc. Some wear and tear of furniture but nothing awful. Only small negative comment would be that I would have liked a superior room but they only have single beds (twin) and not a double which I prefer and available in the standard rooms and suites only.
Basically a friendly place to stay, great location in the centre of Silom, near Patpong but gives peace and quiet on the higher floors. Good value for money and look forward to staying again at the end of the year when I return to Bangkok.More
