My Kingdom for a Table

The physical environment for where you're playing means a lot. Easy answer is a dining room table, they're normally clean creatures that have a solid number of chairs loitering around them. Downside: they're right in the middle of house living and tend to be in active areas of the house, they're not always the most comfortable if the house is going for a colonial American feel, and that nice clean state needs to be resumed after you're done. No matter what you play on make sure its out of the way, having people constantly in and out and making noise can be infuriating. An attic, basement, odd tv room, or even an outside table on a non-windy summer day work nice. Like I said tables and chairs are preferred but if you're young playing on a low pile carpet (for dice rolling) with some friendly backrests is fine just make sure your DM has some defense against higher altitude players peaking over your screen. Other things to consider when finding a space are proximity to a bathroom, is there a TV in the room for breaks/distractions, and definitely lighting. Try out a couple places and be sure to be flexible, its nice having all your books laid out neatly before hand with chips already on the table but if your players want to play out on the deck go for it.
