An’s apartment is just a few (very hilly) walking minutes from the heart of Bairro Alto, restaurants, supermarkets and the Metro. The apartment itself was very clean. The apartment has a washer and dryer which was extremely welcome during a long European vacation where this was the 4th stop. An was very easy to contact whenever required. Self-check-in/out was very easy.
Only issue we ran in to was the front door lock was broken when we first arrived. Someone showed up knocking at the door the first day, speaking Portuguese (which I don't speak) and started measuring the front door lock. It was a bit confusing who this person was and what they were doing as we were not notified about it. The next day while we were out, the same group apparently let themselves into the apartment to fix the lock - again without us being notified. All of our belongings and valuables were in the apartment, and we were not notified that people would be letting themselves into the apartment, which was a bit unsettling when we had passports, electronics, etc. all in the apartment and we did not know someone besides the owner would access the apartment.
