It's a bit dated, but clean; The Admiral Fell Inn puts you in the heart of Fells for your budget or less. There's a cool cocktail bar in the basement (now called Anchor Bar), as well as Duck Duck Goose on the first floor.

The other option in Fells is The Pendry, but I think it's usually between $400-700/night.

Outside of those, any of the global hotels in Harbor East will pretty much be what you get from them in any other city.
