This apartment is totally lovely. It looks great in the photos but is even better in real life. It is generous in size, lovely and full of light with loads of fresh air and lovely and quiet. In fact, we felt we were staying in a secret hotel! We really liked that the apartment was situated a little away from all the crowds and madness down the hill. Sure, it meant that there was a bit more effort to get home after a day out but the buses and trams are excellent and come very often so it really was super easy. And there are cabs everywhere and a really cheap alternative.
The hosts were really helpful and responsive too and shared loads of great tips - and when we had a minor query about how something worked in the apartment, it was all sorted immediately.
I really can't recommend this place highly enough. For two people, it just a perfect Lisbon option.
