The place is really nicely decorated and we had an amazing time in Lisbon.
Although a bit far from the city center, this residential area is a great option to stay in as its really only 20 min walk away from the main areas. The only problem with the area I would say could be the slopes to reach it. If you are young, no problem but if you are a bit older, you will suffer a bit to get back walking.
Regarding the apartment, it had all we needed and almost everything worked well. The biggest issue id say was the Front door of the building, which you need to be a master to open it. Please make sure they explain you the "trick" as we got one day back around midnight and had to call some neighbours to open us.
Also, Wifi, which didn't work during all our stay ( to be honest we also didn't tell Marta about it).
Otherwise, wonderful stay, we really loved Lisbon and would surely come back (now that we know how to open the front door).
