I had a great time at Manuel's Alfama flat. The location was great and the space was very nice and clean. I wish the bathroom sink was a bit bigger, but no biggie. There were a few tiny super markets around the place and a Fado restaurant just around the corner, which was open even after midnight. When I first got to Lisbon, my driver couldn't find his place so he called Manuel (kind of late at night) and he came to pick me up and carried my suitcase for me! He was very helpful and nice. I'd love to stay at his place again.
The only downside was that no one could find the place easily. A car rental company came to drop off the car but it took about an hour because it was hard to find. But it really isn't hard to find by walk and it's very safe neighborhood to walk around at night too. I walked around a lot at 3-4am after a night out in other neighborhood, but never felt this safe and comfortable to walk around.
