We had a great stay for 5 days in this apartment, it was perfect for 2, very well located near the Martim Moniz metro station, nice local cafés, restaurants and shops. Also really close to St George's castel, and St Lucie's miradouro, with amazing views on the city.
Ana was very nice, welcoming and recommended us great places to visit or eat, took care of us when we had a wifi problem and was responding very quickly to our questions during our stay.
Walking and climbing is Lisbon is mandatory, so we were not surprised with the stairs to get to the apartment. Good workout to stay in good shape ;)
