This property is a great off-location hotel with the infinity pool and all the slightly nicer perks you don't really get with the other hotels. Most importantly the property is still new, so the staff are very willing to go an extra mile to accommodate to guests, especially elite folks.

Depends on what you value and what you want to do? BKK is a big city, there are many districts offering a different atmosphere. Most people stay at the chitlom/saladaeng strip along the BTS because it's where all the mega malls are concentrated at, and all the 5 stars chain hotels all set up shop there, and you literally do not need to cross the streets on the ground, they have skywalks that links you from malls to malls, which is extra helpful in the sweltering midday heat.

If you are a fan of night markets/street food/wholesale shopping malls like us, try researching the Novotel at the Platinum Mall. It's a little far from the BTS (say 10 min walk), but you are in the middle of literally everything. They have night markets that go from 6-7pm to 1am, and another group set up shop from 4-7am, you also get the regular street vendors spread through everywhere through the day as well. It's also beside the canal where you can take a 100 baht boat ride to the main river that takes you to Chao Phraya River.

Back to your question, depends on what kind of action. The nightlife and bars at Silom are about 15 min cab away. If you want to go to those fancy restaurants in Sukhumvit, can take up to 30 without traffic, sometimes an hour or more during peak hours.
