After having traveled through most of Spain, I wanted a quiet, calm place to stay for a couple of days before seeing the rest of Portugal. Ecoaldeia was exactly what I was looking for! The farm has an easygoing, casual atmosphere, and you can interact with people as much or as little as you want. Everyone seemed very friendly! No locks or keys, so you just sort of stroll in through the open door. The shower is a bit quirky, so you might have to fight it a little, and with the house being so open, you might have to contend with an annoying fly or two. But those tiny issues were mere footnotes for me. The farm has the rustic appeal I was hoping for.
The town is rather isolated, but it's got the essentials--a grocery store, a cafe. The hiking around the town isn't gorgeous or anything until you make it to the coast (I highly recommend visiting Azenhas do Mar), but you walk on quiet backroads, through even tinier villages. It's all very quaint.
Do note that the farm's driveway is a bit farther down the road than you would think, and when you find the number, both driveways lead to the main house. The bus there is very infrequent, so I recommend using Uber to get around when you don't want to walk.
I would stay here again!
