This apartment is in an amazing area, walking distance from tons of good restaurants, bars, shops, sights, and if you've got the knees for it, you can easily walk all the way down to the water's edge. The beds are super comfy, the kitchen is generously stocked, the building itself is amazing. Everything looks exactly as pictured, the private yard is gorgeous and the flowers are super well-kept. The view from the shared courtyard is incredible.
The building was very accessible by Uber. We took Ubers to and from the apartment constantly with no issue. The doormen were all very friendly and helpful, though they didn't speak English (that wasn't a problem at all).
Our only complaint is that there was a strong smell of mildew while we were there. It had been raining in Lisbon for nearly a month, so it was no fault of the hosts, but this was unpleasant and airing it out did not help. I was told it's not typically like this, and I understand it was due to the unusual weather.
