We had a great time in Lisbon! The location of the flat is perfect, very central and public transportation can be reached easily in a couple of minutes walk. The flat is very nicely furnished and we had everything we needed for our stay. Carlos was there to show us the flat and hand over the keys.
Only negative points would be that you can hear the noise from the street and the neighbors, which can be annoying at night. Also wouldnt recommand this place for people with mobility issues since stairs in the house are very steep.
