I was here 9/4-9/11/22 for my daughter's wedding in Harwich, her in-laws live in Brewster a 1/3 mi away. House had everything you need to cook -we had some meals at home, and hosted a small cookout for a few hours one day w/12 and worked perfectly, plenty of seating, all were comfortable. You can't park on the streets here, but we managed to squeeze in 6 cars in the drive during the one cookout, rest of time was just 2 cars. Stayed mostly just 2 of us, until my brother joined us for last 3 nights. Plenty of room for us, 2 baths, 3 showers (outdoor was nice, makes it a beach house!). Beds were comfortable, area was very quiet. Didn't meet the owners, tho I think they are next door, if weren't for connections already w/ the area, might have stopped by to ask thoughts- tho the house book is very thorough as well. Walk to beach is short, Brewster Flats are something to see! Lots of shopping for your needs very close by, so no worries there. With the large family contingent in other areas, we only explored up to Provincetown one day (artsy pretty town w/plenty of eclectic folks in a pretty setting) while others took in Nantucket and other areas. Did ride bikes (we have road bikes) and saw lots of other beaches, didn't stick w/rail trail, which is super bike friendly.
So, plenty to do, well equipped house and comfy beds. You'll be pleased if you rent here!
