We had a great stay in Diogo and cousins apartment. The apartment has a central location so ideal for exploring the city.
It is a spacious apartment with 5 of us (3 adults, 2 children) being very comfortable there. It is very well kitted out with anything you would need e.g. A very well equipped kitchen, wi-fi, washing machine etc
What really stands out is the service we got. Gustavo collected us from the airport, gave us a tour of the city on the way to the apartment and then sat down and gave us tips on what to do and see during our stay. To top it off he dropped my mother back to the airport when she was leaving.
Vanda was also able to organise a trip to Fatima and Obidos with the highly accommodating Cesar for us at a very reasonable cost.
If back in Lisbon I would definitely stay with Diogo and cousins again.
