All in all it was ok. Let's start from the positive aspects: the position is the best you can have in Lisbon, located Bairro Alto but in a quieter street where you can sleep comfortably.
Hugo is kind and helpful.
Now for the least positive aspects: the apartment (like the building) is old and the furniture of the bedroom quite antiquated. The bed and pillow weren't the best. Overall cleanliness could be a bit improved, in my opinion, especially in the bathroom.
I don't know if you can get any better for this price in Bairro Alto, as it's a very expensive area. I have to say I was a bit misled by the pictures and was expecting something a bit better.
Still, it was an ok experience overall, and the position is unbeatable.
