Absolutely beautiful apartment. Comfortable beds and well stocked kitchen. It does only have a range and not an oven though. Not a huge deal but it didn't occur to me to check. Very quiet. Porto's soccer team won a championship game while we were there and I didn't even know there was celebrations until I opened the door.
We were on the 4th floor and although there is an elevator you can't get to it until going up to the second floor (up 1 large flight of stairs) and then taking the elevator. They also asked we don't use it except for luggage which was a struggle when we had a very tired 6 year old that wanted to be carried up to the 4th floor after a long day of exploring.
