This was a truly 5 star experience.
I stayed in two Residentas apartments and both of them were perfect. Spacious and immaculate in the very heart of Lisbon. They are equipped in all things you may need during your stay. There's also very reliable internet available that was important for me as I worked remotely during my stay.
The Residentas staff were also helpful and pleasant to talk to. They were always available during my stay and helped to extend my stay in a very convenient way.
