I liked Column, to be honest, mainly for ‘Long Table’, which is the restaurant/lounge located on the 25th Floor. The complimentary breakfast was excellent, and you can order from a menu in addition to the fruit and cereal bar (where else can you get sushi as part of your free breakfast?). The lounge has a wonderful view of BKK along with an infinity pool and a really nice cocktail bar (although the cocktails are on the pricey side). Being next to Foodland, however, really puts the final star on the convenience aspect. Foodland is an excellent expat-friendly grocery store that is open late at night and has everything you could possibly want or need.
On the down side, taxis have a slightly harder time finding Column than they would a hotel (although saying ‘Foodland’ usually gets them there). While the sky train is close (about a 10-15 min walk), the walk isn’t a pleasant one as it involves walking along a highway and crossing an intersection. On the bright side, taxis are plentiful and cheap (you could always take a Taxi to the Sky Train) and the hotel is close enough to most places that braving the traffic in a Taxi cab isn't too much of a trial.
The apartment includes a full kitchen and a washer/dryer, making it possible to do your laundry on the last day. The two bed two bath suite I stayed in was very spacious, had a nice view, and the linens and towels were of good quality and clean.
Column is a serviced apartment and not a hotel, so there’s no room service or spa within the building (although I would recommend Kuppa Spa, which is about a 5 minute walk away). The rooms, while spacious, aren’t opulent and lack the small touches that would make it equivalent to a five-star hotel. The rooms were clean, nice, but just a little too sparse. The bathrooms, while perfectly decent, could use minor cosmetic repair work here and there.
All in all, I would definitely recommend this place for the convenience factor and the breakfast. It's a great place to come, especially if you a travelling with a larger party and can take advantage of their suites. If you're happy to pop downstairs and buy your own fruit, drinks and snacks and don't mind a slightly more adventurous walk to the Sky Train, this place is hard to beat.
