My family and I stayed at Teresa & Brian's Cascais apartment for around 1 1/2 weeks. Teresa greeted us when we arrived and was super helpful and warm in giving us an overview of the unit. (I typically love a self-check in option but now understanding all that is involved - keys, garage door opener, parking instructions, etc. - it is very helpful to have a host greet you when you arrive. )
The unit is just as nice in person as shown in the pictures. They've put a lot of thought and attention to so many details that made our stay very enjoyable. We especially appreciated them stocking things like coffee pods, soap, dishwashing liquid, etc., which saved us from having to shop for everything right after arriving. The location is excellent. We were able to walk to a nearby cafe for breakfast and coffee, a local market (much pricier than the larger grocery stores like Pingo Doce), and a pharmacy. We had our two kids with us and a stroller so chose to drive to the beach but it's only a 20 minute walk / 5 minute drive away. There are so many good restaurants and shops near the beach.
There is parking but the garage space is so compact we ended up using the free street parking right outside. We always found a space right outside of the building, no matter the time of day.
Overall, we have nothing but positive things to say. They've really earned the AirBnB "plus" status and we would highly recommend this place to anyone looking for a nice home base while exploring Cascais and the surrounding areas.
