Lisbon is a fantastic city and Alfama is the best part of it and the part where Daniel ´s apartment is located. Daniel is a very good host and his apartment is very clean and comfortable for two people. Alfama is very quiet but still there seems to be Fado in every other house there. The transportation can for instance go by the famous tram NR. 28 but everything is very close and in a walking distance.
Daniel waited for us when we arrived (late in the evening) and because of the difficulty to drive inside Alfama he met us at Porto do Sol and walked us to his house from there.
Just for the information: If you are going to the airport very early in the morning (before public transport) it is best to order a taxi Autocoope (Tel: 217932756) or Radio Taxis (Tel: 21811900) http://lisbon-portugal-guide.com/lisbon-transport/lisbon-taxi-guide.php
We used Autocoope and the car was outside our house exactly at the time we ordered it and the cost was E10 (2 suitcases included)
