I had a wonderful time in Lisbon and at Sofia's Apartment!
The place has everything you need really, is located in a beautiful private backyard and located in a lively neighborhood with lots of restaurants, grocery shopping options etc.
It is also very close to my favorite spots in Lisbon: Miradouro da Graça and Jardim da Cerca da Graça.
Highly recommended!
Communication with Sofia/Irene was also very pleasant at all times.
Thanks!
