I had a wonderful stay at Rita's place. She's an excellent host. The place is phenomenal and you should stay here.
Key highlights: (1) Rita met me when I got there and was super friendly / accommodating; (2) she provided a bottle of local Rose which was awesome; (3) the place is wonderful and the outdoor balcony overlooking the town square is a major selling point; (4) high ceilings which is phenomenal; (5) great airflow; (6) peakaboo view of ocean in kitchen is awesome; (7) dining area is fantastic.
Key items that aren't a problem at all but are good to know about: (1) the town square is loud and there is for sure night life close by, so bring ear plugs!; (2) smaller BR has an awesome skylight but no windows that I knew of; (3) WiFi strength was spotty in the bathroom and bigger bedroom on my iPhone... but I have an older iPhone; (4) you can park pretty much anywhere in town, max time I spent circling looking for a spot was 10 minutes.
You should absolutely stay here. I'd book again in a heartbeat if I go back to Ericeira. Thanks Rita!
