Andre's house is the perfect spot to spend a few nights in Lisbon. It's extremely well located and all the good spots are just a short walk away. The bed is comfortable, there is a fan / AC unit to keep you cool at night, and he even has a washer / dryer! In terms of expectations: The room is on the small side and the apartment is modest. This was no issue for me, but just be aware that this is not the Hilton or a luxury hotel. That said, you're getting a REALLY good deal by staying at his place — it has everything you need and it's very affordable.
Even though Andre doesn't speak English we had no issues communicating. He is really friendly and hospitable, too — we had the chance to take a walk through the streets of Lisbon on my first night and we had a blast. Thank you for a wonderful time, Andre! See you again soon :)
