The "village" part of Muntberg is in the walled section outside the Keep. In the "courtyard" in this picture, imagine several more buildings... You notice a Temple to Typhon near the gate and a small chapel to Tyche in the south part. There's a market square, stable, general store, a smithy/armorer, and a few other specialty merchants, like gemsmith, moneychanger, and caravan merchant and several private houses. You all are sharing some private rooms at the mostly empty Green Dragon Inn. Across the street is the Flask and Scroll Tavern.
(You guys can assume that reasonable food/drink are covered. That includes simple fare at the tavern for breakfast and dinner, and a couple of beers. If you want fancier stuff, you can pay more, based on how well you want to live, or go a la carte. Living out of the tavern on simple fare, you're living on about 1 gp/day, but we'll assume the first week is covered)
