Plenty of condos in the South Idrive area or LBV would fit your bill. You can get a 2 bed will full kitchen adn w/d walking distace to restaurants and a $10 taxi to DTD. There are no cleaning fees or extras to pay (you can poay for daily maid but unless you are pigs wont' need one in a week). You book them like Hotles via hotel booking websites.

Cypress pointe is my fav if you have a car for daytime (don't need one at night as there are 10+ places to eat nearby) as they no longer do shuttles to parks. If you don't have a car (which I know you do but this is for others) look at ones on south Idrive. Not always walking distance but are on a bus route to evening places.
