Furama Sukhumvit is located deep into Soi 1 of Sukhumvit Road. The rooms are of moderate size and comfort. Breakfast is, I consider, quite mediocre but sufficient to start each day off. The front desk is manned by very helpful staff who speak a number of languages such as English, Arabic, etc. I noticed that the hotel is well patronized by Middle Eastern people and Westerners. There are not many Asians around during my stay. The hotel do not have a tuk-tuk service and wifi is not readily available.
It takes about 8 minutes walking casually to reach the main road which is usually congested with confluencing traffic from the left flowing from upper Sukhumvit and traffic coming into Sukhumvit from Ploenchit and the adjoining expressway. Soi 1 is also the entrance to a large nearby hospital. This compounded the congestion problem there. Therefore, if you have a stomach to take some jostling and scurrying, then it's alright. The plus here is that taxis are in abundance due to the constant activities.
We enjoyed this hotel more so because amenities are plentiful; such as a small cafe right in front of the hotel serving coffee and snacks for a paltry sum. The resident fruits seller on his pick-up provided a wide array of fresh fruits just across the Soi. Massage parlors are everywhere providing good & cheap services. Soi 1 is really well located for one who wants to go to Terminal 21 and Emporium Mall on your left and on your right of the Soi, you have access to Ploenchit and onto the shopping belt of Paragon, Siam Center, Central World, Platinum Mall, Erawan Shrine and a host of dining options all within a Bht50-80 taxi ride. If you're at Platinum Mall, do not try to get a taxi there as they demand a princely sum to fetch you anywhere. But walk to the rear of the mall towards Central World where taxis are less predatory. Nana BTS is just a short walk on the main road to the left. Nana Entertainment area is just opposite Sukhumvit on Soi 4.
All in, Furama gives rather good value for a moderately-priced hotel. But if you want more up-market accommodations, you could go to Novotel Ploenchit, Landmark Hotel, Marriott, ande a host of higher class hotels along Soi 2.
