What made me incredibly pleased from the moment we arrived is how attentive Pedro was, and how much he made sure we were having a pleasant stay. Pedro made sure we made it to the right place and check on us whenever he had a chance. He even chatted with us during our New Year's eve dinner.
Secondly, the room was quite comfortable, with plenty of space and nice beds. The access to a kitchen was quite a plus, letting us cook our own things instead of struggling to find a good restaurant. And with the subway relatively near it was very easy to go to different parts of Lisbon.
The only issue we had was the cold winter getting to us and the heater not being strong enough, but never to the point it became a problem. If you go during winter, request extra blankets just in case.
Other than that, I can't recommend this place enough.
