Some of the coffee pots in the studios are small 4-cup ones, some are standard size. The larger villas all have standard size coffee pots, and you can request a larger pot from housekeeping if you are in a studio which happens to have a small pot. The pots use the flat-bottomed filters, not the cone-shaped ones.
We always buy and use coffee in filter packs (more expensive, I know, but very convenient for use and cleanup).
