Although my girlfriend and I didn't met personally Sofia, she has been helpful during the whole trip. Her friend Bruno kindly received ourselves for a late check-in (after midnight), and offered us not only his help but also two delicious pasteis de nata. And our addition to this amazing sweets started from the first day!
The apartment is cozy, perfect for a couple, and it has a perfect position for enjoying Lisbon. It is also very clean and has all the stuff you need for a comfortable trip in Lisbon. Rossio metro and train station are at most 5 minutes walk away. Few more minutes to reach most of the attraction of the city center.
I can do nothing but recommend to contact Sofia if you want to go to Lisbon! I probably would to the same!
