We stayed 8 days and it was great. The apartment is exactly as the picture , very clean , the beds are comfortable, the amenities are great( iron, iron board, washing and dryer ) .
The location is amazing , I can't imagine a better place. Many restaurants walking distance, bakery ( Marques de Pombal) , high end stores, Av Liberdade is pleasant to walk. Behind the building you will find an excellent pizza place with a spagetteria attached to it, little bakery, little restaurants with good portuguese food ( very affordable). in the blocks around there is a mini market ( with fresh bread and pastry) , a car rental place , pharmacy.
Close to a subway station , you can walk to Restauradores, Rossio, praca do comercio, Alfama .
I highly recommend Olga's place, I spend hours trying to get the perfect place for our family and this one was great.
