Me my partner had a wonderful stay at this apartment, the views are stunning and location perfect for what we were looking for.
If you are visiting at Winter be aware it is a cool flat best designed for hotter weather, but ok if you layer up. Also worth bringing ear plugs on foggy days as the cruise ship horns can be a nuisance from early in the morning, however as nobody else has noted this, it may be unusual.
Plenty of local good restaurants and nearby cash points and nearby minimarkets if you need them, Local transport also nearby and ubers appear particularly cheap in Lisbon. Kitchen was well equipped and the apartment is much larger than it looks in the pictures.
We would definitely recommend to others. Come and enjoy!
