We had quite a bad experience here. When we arrived in Lisbon, we went to the accommodation office, which is a distance away, were given a code which was fine (we knew this in advance). Then we went to the apartment later but there was not a code reader anymore on the apartment door as it had not been removed. A key was now needed. This had been lost in the process somewhere. Then we had to ring the emergency contact number as even though still during the quoted office hours, there was no answer from the office number. 1 hour later a key (only 1) was finally delivered. very bad experience which ruined our first night.
On the second night the residents (only 1 permanent resident in the building of 6 apartments, 5 are for rental to tourists) had a very loud shouting match with people staying in another apartment as they were making noise. This went out until nearly 3am. So note that there is a chance of this happening again as there is only 1 resident and 5 tourist rental apartments. The location is good. The flat was generally clean except the toilet brush which was covered in poo - disgusting. The only oven dish was also dirty with grease.
