If you are visiting Lisbon, I really don't think you could get a much better situated apartment than this! Ok let's get one thing out the way - there is road and tram noise, but nearly every review states this so it shouldn't be a shock to any guest and if this is going to really bother you, then this might not be the apartment for you.
I visited with three girlfriends, we ate out for every meal so I can't comment on the kitchen facilities as we didn't use any of them, but it appeared to be very well equipped and included a dishwasher & washing machine. The apartment was very clean & comfortable.
Access was via an electronic key on an app which you download prior to your visit. Communication with Sulamita & Ricardo during our stay was very prompt.
The apartment is in Baixa-Chiado, so great for sightseeing and visiting restaurants. Lots of places are within walking distance & if they are not, (or you don't like walking up hills,) it is dead easy to hop on a tram, bus or metro. (tip - buy the 24 hr ticket). Various stops for various routes are all nearby.
(Treat yourself to breakfast over the road at Paco-Real. Rammed with locals and The Best! brioche, croissants & coffee!).
We all said that we wouldn't hesitate in returning to, or recommending this apartment to anyone wishing to visit Lisbon. Fantastic find.
