We enjoyed our stay in this apartment! It was clean and comfortable and the location is fantastic to enjoy Cascais...and right next to the train station which was perfect for a day trip into Lisbon or elsewhere. The beach was right around the corner and perfect walking distance even with our toddler.
The rooftop terrace was a lovely feature! Very nice in the afternoon sun.
The only negatives I would mention are not a reflection of our host, nor did they have a big impact on our enjoyment...but it can be very noisy in the earlier hours of night, as it is on a fairly busy street so we would often hear boisterous voices from the McDonalds area next door while going to sleep, and the weekend was especially loud.
Also the apartment feels very chilly in February without the use of the wood stove, and staying with my toddler I preferred not to have that in use as it is directly in the living room and I was worried she might accidentally bump up against it and burn herself. But we relied instead on the electrical heaters that were around the apartment and this was suffice, so I appreciated that Joana provided these as well.
Also, it's important to pay attention to the description of the layout of the bedrooms, as I didn't realize until we arrived that in order to access the washroom and the rest of the apartment at night from the upstairs bedroom, you have to pass through the bedroom on the bottom floor. This was awkward because we were staying with another couple and it was an intrusion of their privacy at night if we needed to go downstairs. It is stated in the description that the bottom bedroom is a passage way, but because it states "two doors", I misunderstood it to mean there was an alternate access as well. Just a heads up!
Overall our stay was good and Joana was great to communicate with though we didn't actually meet her, and Sarah welcomed us at the apartment. She was also very nice. If we needed anything, Joana's shop was very close by and we would drop in there while out and about (for example, to pick up an extra key for the other couple, and to drop them off again at check out). Sarah works there and we also met Joana's husband briefly at the shop.
A very nice apartment in lively, beautiful surroundings!
