Before our ( girlfriend and I) arrival I messaged Sylvie with many questions and she was very nice &responsive. Then before my flight her flat manager Paulo, message me to find out when I arrive. Paulo was extremely helpful , really a great guy. Once we got to the apt Paulo waited for us, he showed us the apt and advised on good places to see. The apt was exactly like the pictures and we were very happy about that. It suited to all of our needs and even more. We come from a warm country where a/c is everywhere, there isn't one in the apt, I told Paulo, and he made surr I'll get a ventilator.
The location is in a very nice area, Lisbon is a difficult city to just walk all day so we took taxi to most places. Overall our stay in the apt was wonderful I highly recommend you stay at Sylvie place.
