We stayed for six days in this apartment and enjoyed the flat a lot. The flat is very cozy and very well equipped. The location was perfect for us, the street was calm but in 1 min you could be at the life of Graça, and in walking distance of the center of Lisboa . The only thing we did not enjoy too much was the bathroom, the water would switch from hot to cold just like this and the toilet didnt smell so nice, but I guess this is due the age of the building, so we thought this is fine and just comes with the beautiful old building and flat.
All in all great, as described and you could see that there was a lot of afford put into making it a comfortable place and stay. Very worth it!
