We had a really good stay at Saint Paul, 3rd floor !
The apartment is nice, spacious, clean and very well equipped (you can easily cook, wash your clothes, there is wifi, a phone that you can use for your restaurants reservations and a hair dryer for example), the location was perfect for us (close to the metro station Cais do Sodré, to a huge food market or a famous bars street and next to the other neighborhoods by feet). The reception was very good. Joana came with pastéis de nata and a lot of precious advices.
Thank you The Blue House for our very nice stay. We really recommend this apartment !
