For me, the place and location are both clean, safe and secured. The apartment is 2-min walk from metro station (which takes you about 10-15 mins on metro to central Lisbon). There are parking spaces (not covered) but very safe. I parked an Audi and never got it damaged or anything.
The apartment is very well equipped for cooking (we did both European and Asian food). There are dish-washing machine, clothes washing machine and clothes drying machine with all detergents and liquids needed.
The check-in was heartwarming. They are extremely nice people. I've got everything I needed during the stay, including all my questions answered.
We haven't met Antonio ourselves, but meeting with his charming brother (Joao) and their nice mother.
I didn't only get a host. I've got a friend ;)))
Would definitely recommend and come back here again!
