I stayed here for a month. You won't find a better location in Cascais, just a few minutes' walk to the beach, train station, grocery store, farmers market, restaurants. It's off the main street so it's very quiet and I slept great. The place is modern, light and bright, internet is excellent, kitchen is well-stocked with everything needed for cooking. Comfy bed, great shower, a heater for cold nights, a washing machine and a rack for drying clothes (no dryer, which is pretty common in Portugal). Sofa and chair cushions have seen better days and frankly could use replacing. Communication is excellent - Katia and Cassie were incredibly responsive. The night I checked in I asked Katia for a desk to work from home and it arrived first thing in the morning. There was a bit of construction both inside and outside the building during my stay, so a few days were noisy. But I found this pretty frequently as I traveled across Portugal; there's just lots of renovation going on. If it's an issue for you just ask if construction is planned in or near the building before you book. Enjoy the little wine bar directly behind the building and lunch at House of Wonders. I'd definitely stay here again!
