For my girlfriend and me staying here was one of the best ways to experience Cascais, Lisbon and Sintra.
As we felt that, while Lisbon is beatiful and well worth it to see, it didn't have a huge amount of different things to do and see. So being near to the beautiful Cascais as well was great.
The apartment is nicely decorated, was clean and had even more than the ameneties and extras we were expecting. Tiago had a huge supply of coffee and even some leftover food like pasta, so we had a quick dinner after our jurney. Tiago even left us some masks and desinfectant because of the pandemic.
As tips for others I would recommend to be cautios about opening the windows (especially the bathroom one), since the bin or some kind of small canal outside smell a little bit at some points during the day. This is in no way related to Tiago or his apartment, just to the location and it wasn't a problem, just a thing to keep in mind. Also the busses going to Sintra either aren't going or going weirdly, so I would recommend to take an Uber or come from Lisbon.
