Ulrik's place has the best location!
You are just 50 or 60 meters away from the Miradouro das Portas do Sol (that you can see, together with the stunning view, from the apartment), and right next to it, the Miradouro de Santa Luzia. It was so charming waking up and look outside... in the late morning, when tourists are out roaming the city, you could hear live ambient music from the little square at the Miradouro das Porta do Sol, straight from your window. The whole atmosphere was regenerating for me!
Location is central, and the stop for the famous tram no. 28 is just a few steps from the front door, and with one ticket you can take a long, scenic tour of Lisbon one the most typical means of transportation that this amazing city has to offer!
My stay was overall pleasant. Self check-in was very easy and he sent details instructions about it. As other reviewers said, the place is undoubtedly small, especially the bathroom and the sink in the bathroom was somewhat smaller than the one I used to have in our old RV. But nonetheless it was cozy, modernly furnished and I really appreciated the AC, since I was travelling in the summer. I didn't hear any noise from outside as the windows are very well insulating. I wish I could say the same about the upstairs neighbors (that I think were other travellers, so this could be very random), but this is not Ulrik's fault.
