The Yellow House was such a comfortable place to stay for our family of 3. Our host came to personally check us in & out, and was reachable for any questions via Whatsapp during our time there. The unit is in a quiet, local residential area (not touristy) that is just a 10-15 min walk from shops and bus/train stations. Cascais also has great restaurants everywhere, which you may have to drive/Uber to, but we found a very good neighborhood restaurant within a 5-min walk.
The Yellow House is bright, airy, and clean, with a nice shower and very comfortable queen beds. The unit in real life is more spacious and nicer than the pictures on the listing. There's a washing machine and clotheslines for you to dry your clothes in the big balcony, but you may need to bring your own laundry detergent. Otherwise it has most other amenities you may need during your stay.
I highly recommend staying at the Yellow House, especially if you're doing a longer stay and don't like to live in super touristy locations, but still be within a 10-15 min walk to most sightseeing. The unit and the location gave us a more realistic experience of living there rather than staying in midst of the action with all the hotels and apartment buildings that mainly cater to tourists. In conclusion we were very happy with our stay!
