We spent one night at the apartment and it was very pleasant. It is optimally located, in the very centre of old Lisbon and close to the metro. There are restaurants and facilities all around. The apartment in itself is very tidy, practical and quiet. A good place to stay. We definitely recommend it. We also would like to thank Ana Paula who welcomed us at the apartment and was very nice. We didn't meet Cristina, but the communication with her was fluid.
