GreatStay was really a great stay. The location is very good: all in walking distance, easy access to Metro, busses and trams. Good shop/Mercado nearby. Apartment was very clean and Klaudia (the owner) answered quickly to all messages. She was already waiting there when I arrived and was very helpful. She made me feel welcome. There was radiator in the room because the weather was cool in Lisbon. The room was very warm and cosy. I can warmly recommed!
