I just checked the price for my favorite - Adelphi Suites. Its more than Arcadia, but I can attest the location is great and I usually get the 1 room suite which has everything you'd ever need for a long term stay (kitchen, washer/dryer). Also I will admit I've stayed there 3 times so far so I'm biased.
It does not have a balcony that I've seen, sorry. But in all other ways it's pretty stellar and roomy. And I've never had a problem with any action.
