Overall a good experience. I wish we'd have known how much his place is located in the middle of a touristy party area. On weekends, this means music and screaming until morning. With the windows closed it was ok, but then it gets hot.
The location on the other hand is very central, so it's perfect for starting the day in Lisboa without using the metro.
Comminication with Pedro was rather poor, i've asked him him a few questions and favours in advanced, which he completely ignored; I assume he was busy. He left the key for us so we could check-in even late at night. The appartment was good, had everything we needed, overall it was clean, but not very clean.
