I do not normally stay in this area but when I do this is a good option. It is quiet but close to the BTS line from two different stops and close to malls and shopping.

I liked the big room and full kitchen.

Stayed for seven nights in a Premier Room, high floor Sathorn side. Booked 2 Rooms. Previous stay around 12 months ago. Hotel/Rooms are getting to the stage where a refurbishment is needed to freshen up its presentation. Problem on check in with room types (hotel claimed misunderstanding with Expedia), after I provided evidence of the correct room type (had to log on to my Expedia account) the issue was resolved - however the process was a bit tedious especially as we had just got in from a long flight.
On a previous visit I commented on the friendliness of the staff, and this has not changed, the atmosphere is very friendly from reception staff to housekeeping.
There is a "happy hour" from 6 -7pm each day when beer, soft drinks and snacks are free to guests.
The location of the hotel is great, tucked in a small street near the Belgian Embassy note: some taxi drivers may have difficulty finding it so make sure you have it marked on a map for them (preferably in Thai). It is minutes from the clubs and nightlife of the Silom area and Chong Nonsi Skytrain Station which can whisk you to most of the main Bangkok attractions and shopping.
Premier rooms are spacious and comfortable. Breakfast is plentiful variety and good quality.
Overall a pleasant stay and would stay again in the future.

Been back to the Furama in Silom/Sathorn - not to be confused with the Furama Silom, on Silom road which have been newly reopened.
Whilst i did have a couple of admin hiccups - i asked for a higher room north facing, and got a slightly lower room south facing - but to an upgraded room. Asked to be down graded 2 nights into 6 night stay as lower rooms have a shower - which i prefer.
Good to note that with the airport skytrain operating, it took me and my baggage 55mins from hotel door, to walk to Chong nonsi, change at Siam, off BTS at Phaya Thai onto Sky train and into Airport. This cost me the astronomivcal sum of 80thb. or U$2.50.
This was leaving the hotel at 4.45pm into rush hour, cannot do that in a a taxi fro 400thb.
Hotel is always good, staff are helpful, breakfast is simple, but more than adequate prices are slightly up on what i have paid before, but i nearly missed out on paying U$29 per night on expedia.
Whilst on the subject of Expedia, their policy of informing you at the last minute of a price change, inevitably upwards is frustrating and tantamount to bait and switch.
back to the hotel - they still offer a 'happy hour of free beer or juice for guests from6 - 7pm, nice touch and great way to end a hectic business day and get into the nightlife mode.
Will be back again.
