Oh. Wow.
Luis' place is *amazing*! The location is unbelievable: amazing view overlooking the Praça de Lisboa and the Igreja dos Clérigos on a pedestrian-only street. It's also just a few doors down from Livraria Lello, the bookstore that supposedly inspired Harry Potter's Hogwarts.
It's adjacent to the University, and some of the best pastries at Padaria Ribeiro are just around the corner. Easy walking to and from Sao Bento, and down to the river or across to Gaia.
And Luis' flat itself is incredible. It's spacious (I think our Airbnb in Lisboa would have fit in the front room), high ceilings, and two full bathrooms.
Not to be overlooked is an elevator. We used the extremely cool staircase most of the time, but the elevator was certainly handy when we had our luggage.
Luis himself was also very friendly and communicative and responsive.
The only thing we could have asked for was more time staying there!
