You can't go too far wrong with the Tryp group of hotels. They are generally up-to-date and professionally run with all the things you need for a good business trip hotel - free wifi, comfy bed, quiet room and efficient reception staff. Decent gym too.
One complaint - the doc you sign when you check in has all sorts of marketing blurb opt-outs which are so small they are barely readable, even with my eyesight which is better than 20-20. This is misleading and very poor from such a respectable hotel chain. You guys really do want to sort that out.
