The Blue House was perfect. Just like in the pictures & description it was clean, comfortable, and well stocked. Check in & out were very easy and the location couldn't have been better. The bus from the airport dropped us a short 3-4 min walk to the apartment. Ines & Antonio left us fruit, bread, and coffee, as well as cold water & milk in the fridge. They were available & willing to help and answer any questions we had.
The apartment is on the 3rd floor (2nd floor in European terms) with no elevator. That was not a problem for us but if stairs are an issue you may want to rethink this. We were very happy with our stay and will definitely stay here again if we return to. Lisbon.
