New Siam III looks pretty shabby from the outside, but once you are inside it is A-OK! I upgraded my room to one with a balcony for about $8 a day more, and it was very much worth it. The receptionist was very helpful for all of my needs. The place was very clean which was great and it was fairly quite, though due to it's location you could hear the occasional loud drunk person from time to time. And they only clean the room when you ask them to, which for me that was nice... My only complaint was that I had to take my laundry service to their other hotel, but it wasn't far and they delivered it back to me, and they almost lost one of my bags, but thankfully they found it. Anyways, this place was great with a great location, I would definitely stay here again.
This was the third time we stayed at New Siam 3 and we have been impressed every time we stay here. It is conveniently located with a 3-5 minute walk to Koasan road. The immediate area around the hotel has a great vibe with a relaxed feelng. The ferry taxi pier is a 5 minute walk and if you use the orange flag taxi you can go up and down the river for 15 baht one way. The hotel is well maintained and we will certainly stay there again when we return to Bangkok.
