This is a really unique apartment in the middle of Alfama - we arrived at the perfect time for the party atmosphere of the Festa at the end of June.
It really gives you great feel for the old town, but it is busy and loud with music until fairly late in the evening during June - we loved it though!
Joana was very accommodating and friendly, she came and met us to show us around, and also gave us some great tips on where to visit and eat some traditional Portuguese dishes - we went to several of the places she recommended and they were all excellent.
Word of warning if you have accessibility requirements - the Alfama area is full of tiny streets with many steps up and down to get to the apartment. Again, no problem for us, but if you have difficulty walking, maybe double check before booking.
This apartment is a great way to get into the spirit of the old town of Lisbon, especially if you come for the Festa... highly recommended!
