This is a Charming family-run Hotel. English friendly and very helpful with finding things in the neighborhod and such. Clean, orderly, recently remodeled - I liked it a lot. Actually moved to this hotel from a larger Hotel 300 feet away. The other Hotel had mold/air quality issues with their air conditioning which was in all three rooms of our group and many immediately came down with sore throats and respitory complaints - classic stuff you see in various hotel reviews in Thailand. The Myth-Sud was great! One day/night and I was back to normal. Many of my friends went home sick on the plane. Only thing someone might consider is road noise. The rooms do face the road but I felt it more like white noise. They do provide ear plugs on your pillow like mints. So if you're super sensitive maybe it's not the right choice.
While the Sathorn area is the only place I stayed both times in Bangkok, I enjoyed it. Price wise it's a little less than other areas and this hotel in particular was a straight shot to the BTS and Sathorn Pier/water Taxis (5 minutes) which are a good ways to get around, as well as tuktuks.
I would definitely stay there again. The price is right and the people are great. As I checked out at 3:30 am I don't know about the breakfast but I'm sure it's just fine. Just remember none of these hotels, at any price point, are our western style Hyatt Hilton Marriott - and that's the point of travel anyway, isn't it?!
