Let me start by saying that Cyril is simply one of the best hosts we have had on Airbnb. He was there to meet us, helped us with our heavy luggage and even helped me find a parking spot for the car. Cyril shared his precious recommendations with us and was very responsive to our needs and questions. There was even ginginha to welcome us :-) It was very good!
The apartment has been renovated with taste. It was very clean and had everything we needed. We were happy to use the washing machine. There is air conditioning upstairs (living area). It is close to LX Factory, grocery stores and restaurants (we recommend Luzzo Pizza, La'Vanda and Quimera Brewpub nearby, good food, nice owners).
For those who have a car, there is free parking in streets and other parking lots nearby, but also a paid parking lot (10 euros a day) right behind the apartment. I recommend to use the car for day trips only or to go to Belem (since there is free parking near the tower). Public transportation is close by (tram, train, bus), so a car is definitely not required.
We are from the suburbs so not used to city sounds. The bus does pass very often in front of the apartment and it can get quite noisy. There was also a bit of a sewage smell downstairs, as it can be expected sometimes with old buildings in historic cities.
Overall, we had a great stay at Cyril's and definitely recommend it! He has guest experience at heart.
