I went to Furama in Singapore and was expecting similar level of the building and facilities. This one at BKK Silom seemed much older and dated, in need of renovation and upgrades, particularly at the main entrance and in the lobby, and overall the infrastructure (e.g. access cards are the 1980s slot type). On the plus side, the rate was affordable. My standard room had a bathtub which was very welcome.
Transport: Be aware that the BTS/MRT are a bit of a walk away (15-20 min), but the Grab is convenient in BKK.
Food: Hotel breakfast is "ok". Outside food: not much food around, esp after dark, aside from a rather sketchy night market near the Hindu temple. There's however a nice Japanese ramen shop about 5-10 min walk away, and several good coffee shops.
