As I get older, it's getting harder to stay at the Pranee Building. It's old. I stayed in 2005, and returned five years later, and not a single thing had changed, including, I imagine, the sheets. No updating. No maintenance. It's a worn down, slightly better than a backpacker-style place with good (though loud) air conditioning (but not in every room) for prices that are hard to beat for a major city like Bangkok. I love the location, across from MBK and right down from the end of the Silom line of the Sky Train (National University Station, I believe). But, the beds are old and not of great quality, the furtniture looks like it was dragged off the street by people who left it, and it generally has a dusty feel to it.
Don't get me wrong: I love Pranee, but it doesn't have the level of comfort that I'm starting to require as I get older. During my last trip to Thailand, I stayed at the Pranee three times. I also stayed elsewhere and paid more for better accommodation. That said, these folks are reliable. When they take down a reservation, they honor it. I've never had a problem with them, and they've always come through. I would simply like a better bed. And maybe even some blankets.
The restaurant attached to the Pranee is also servicable. It's not going to wow anyone, but it gets the job done and is always a base-hit.
I prefer places like the Pranee and Siam Square to any of the types of places up in the Khao San area. I could also like Sukhumvit, though I've never stayed there. For what it is, it's unbeatable. Most of the folks reading this, however, will likely have outgrown this style of accommodation long before arriving.
