Our stay was perfect. Since we were beginners we didn't know what to expect of Airbnb. But Mario and Maria made us fan from the beginning. They informed us well and responded very quick on mails. They were so nice to arrange a taxi for us when we arrived. The house was really nice. We loved the decoration and facilities. Did use the bikes a lot and although we didn't use the kitchen for cooking we think everything was in it.
Ericeira is a lovely town. You can enjoy the really nice sunset, good bakerys and restaurants and there's enough to do. A bikeride away you can take the bus to Mafra (approximately 20 minutes), Sintra (50 minutes) and Lisbon (70 minutes). We also rented a scooter for one day (only 30 euros at Go Out) and took some surflessons (25 euros for 2/3 hours).
