Filipe's place is a really nice one. We did not meet him but check-in was really easy and everything we needed was available (towels, kitchen stuffs...). It was really clean and cosy and we had a lovely time. It is not right in the center of Lisbon but at a really walkable distance so it is fine. We had to be at the airport really early in the morning (4pm) and it was not to difficult to get there as a night bus pass just near the appartement.
