Our family stayed in the apartment for more than one month and it was one of our best stays in Lisbon! It is located in a perfect central business area - Avenidas Novas, close to the metro and main attractions.
The apartment is recently renovated and decorated, light and clean. The kitchen was the most comfortable and convenient place - it was a pleasure to cook and have family dinners in it.
Upon arrival, we detected a problem with a drain hole in a bathroom and informed the host about it. The problem was solved right the next morning although it was a national holiday in Portugal on that day.
The nearest supermarket is 1 min from the entrance, a big shopping center is 10 min of walking and the cozy Gulbenkian park with ducks and green grass is also very close.
I would definitely recommend this apartment for long and short-term stays in Lisbon.
