We really enjoyed staying at Tiago's apartment. It's very clean, and the location is phenomenal - you can walk everywhere, but also the station for any out of town trip is right there.
The space was clean. I enjoyed looking out of the balcony in the mornings. Everything works well, the beds were comfy.
Tiago is a fantastic host. He really went out of his was to make our stay enjoyable: not only did he greet us with the best pasteis de nata in town but also so helped us crazy our heavy luggage from the 5th floor upon our arrival and departure.
If I ever return to Lisbon, I would definitely stay here again!
