Our stay in Thierry's apartment has been really positive: Thierry welcomed us at our arrival and he has been very friendly, we actually arrived earlier than expected but he was already there. He showed us the apartment and gave us useful information about the surroundings and the parking (we visited Portugal by car!) and provided us with a map and an Italian guide on the main attractions in Lisbon.
The apartment was comfortable, equipped with all the basic - and non-basic too - facilities, and furnished with taste and care.
The terrace is a very lovely plus!
The neighborhood is quite calm; very next to Alfama, the position is convenient to visit Lisbon by foot or by public transportation: tram and metro station are actually really close.
We certainly recommend a stay in Thierry's apartment!
