It was the first time I used Airbnb for a trip and I was not disappointed at all.
The appartment is perfectly fine, there is more than enough room, it's clean, you can cook by yourself and everything worked out great.
Zé helped us getting an overview about Lisbon and showed us some places to go on he map we got from him.
We could've called him when something was wrong, but since there wasn't any issue, we didn't had to make use of it.
