I stayed at João and Dora's place for 3 weeks while working in the NOVA University (in Caparica)!
Their apartment is just amazing!!! Stylish, always clean and very big! My room was very nice , including all the necessary amenities (double bed, big desk, chair, 2 wardrobes and many more). Also, the bathroom was very big and always clean! The kitchen was very spacious (I had my own place to store my groceries and be independent). In general, the house is quiet and this was very important for me since I was studying a lot.
Now, the location is one of the best you can find in Lisbon, with the São Sebastião metro station literally next to the house. Also, Praça de Espanha (bus station) is only 5 minutes walk from the house (I was getting the bus towards Caparica every single day). The neighbourhood is quiet and you can have nice walks around there. A really big shopping center (El Corte Inglés) is also 5min away from the house and I found this extremely useful! I could easily go to the supermarket, for shopping or even for dinner/movie there anytime that I wanted to!
But most importantly, João and Dora are by far the best hosts I have met so far! They are very polite and always smiling! They gave me tips for restaurants/sightseeing in Lisbon with great pleasure and they respected my privacy too! Moreover, we had dinner together plenty of times (also BBQ) and we had the chance to discuss and meet each other better! I literally felt like home and therefore I am very grateful for their hospitality!
I totally suggest this place to everyone and I would stay there again without any second thought! Actually, I am looking forward to that! :)
