Luca is a fantastic host, great communication throughout and apartment was easy to find - just make sure that the taxi driver doesn't take you over the bridge - it happened with me once (the first time I went) but that was the only time out of about 10 trips. I was worried about the flat being warm but the flat was nice and cool, even when the sun was hot. WiFi was super, location is great, plenty of local shops and parks nearby. Highly recommend Luca's flat for any visit to Lisbon, whatever the purpose.
