It's been a while since your post, but I wanted to offer some insight. I get where you’re coming from. I once stayed in a high-rise condo for a work trip, and while the views from the 50th floor were incredible, I was also worried about the legality of short-term rentals. I ended up feeling more at ease knowing that the building had clear rules and my host was upfront about everything.
The Amara Bangkok sounds like a solid choice, especially if you’re after a new place in a good location. I’ve had good experiences with serviced apartments myself, and they often strike a nice balance between the amenities of a hotel and the comfort of a rental. Plus, if you’re into the business class experience, it’s worth noting that staying in a well-rated place can make your whole trip smoother and more enjoyable. If you’re comfortable with a hotel’s services and location, it might be worth considering, especially for a two-week stay.
