This is a great, clean, quiet place in Lisbon. Maria&Pedro speak excellent english and are very fast at responding + are available for any questions during your stay. Since they are very busy though, we didn't have time to get to know each-other. but when Pedro presented the appartment, he took a lot of time to explain all about sights, transport and orientation in Lisbon, very valuable information if you didn't read anything about the city beforehand.
The appartment is very well equipped and everything is working great. There were some teabags and coffee capsules (with the machine) to get us started.
Note : If you're travelling by metro from the airport, do know that this appartment is at the top of one of the seven hills of the city ^^ Consider taking a cab with your luggage like they suggest. We definetely recommend this place !
