We had a lovely stay in Lisbon and in this apartment.
Our expectations were addressed, the apartment is very comfortable, great location nearby the metro station (<10min walk) with an Auchan supermarket nearby.
The apartment is located on a steep hill road, so take this into account if you have problems walking. We had a rental car and we parked it on the street (free during weekends, our case) and left there for our entire stay.
Great view from the apartment, we found some complimentary coffee and shampoo/soap, perfect for a 2-nights stay.
Check-in and check-out process very easy and precise, communication with the host was timely and they also gave us good tips to visit Lisbon. Would definitely come back and recommend this place!
