PERFECT in so many ways ! (Just make sure you space out your showers an hour apart, at least). There are so many positives about this apartment, we really enjoyed our stay.
LOCATION: On one of the parallel streets (smaller, no car traffic) between the Arch (Arco da Rua Augusta) and Rossio Metro. Lots of transit options (bus, tram, metro), many restaurants on those parallel streets, several small grocery stores, Bakeries galore, and it's a FLAT area of Lisbon (no hills to climb). The unit is on the first floor which means only 1 flight of stairs up from ground entrance. We heard minimal to NO street noises although we did travel in April when it was cold and not a lot of people ate outdoors.
INSIDE the unit: Great design - toilet and small sink in a separate room from Shower and big sink, makes sharing the facilities so much easier. Kitchen well equipped - has washing machine, kettle, microwave, Brita water filter, toaster, coffee maker. Quite a few mirrors hung throughout, handy for everyone to have their own space make up/ hair curling/grooming.
One caveat: we found out that the hot water tank only has enough hot water for 1.5 showers. First person's was fine. For second person, the hot water ran out halfway! Planning ahead will help.
Communication: Leonel was the local rep for José and he was very responsive and helpful on whatsapp. We were able to drop our luggage early and picked up the keys while the cleaning ladies were still cleaning the unit.
We highly recommend this property for anyone visiting Lisbon.
