Ana's place is a wonderful apartment in the centre of Porto. The apartment is comfortable and private, with a well equipped kitchen and plenty of space. We loved the location - you could not be closer to Sao Bento station so ideal for travellers without a car. We were able to easily walk everywhere we wanted to go sightseeing too.
Ana was a very generous host who spent around half an hour showing us all of the attractions we should visit and marking them on a map. She was very friendly and helpful.
I suggest that you arrange to meet Ana at Delices Cafe which is right next door to the apartment. It saves you waiting on the street and for those that do not have mobile access, there is wifi (requires a password, but order yourself a very inexpensive coffee and ask the lovely lady at the counter for the password).
Highly recommend Ana's apartment, 11/10 would stay again :)
