I had a wonderful time in Filipe's apartment. It was very clean, modern and comfortable. The location was just excellent, very easy to get anywhere in Lisbon from the apartment. Also there are some wonderful little cheese and wine places right on the doorstep pretty much! You must try 'The Corkscrew' for excellent Portuguese cheese and wine.
I found Filipe to be very polite and easy to talk to. He is a lovely host who was happy to answer any questions we had.
Lisbon is a fantastic city and I can't wait to return as 4 days is just not enough!
