While I did have a lovely stay in Lisbon, and the room itself was very large and sunny, my stay in Camila & Paulo's apartment was far from outstanding. I ran into many avoidable issues during my stay.
Check-in was not great - I received no information about checkin until I explicitly asked the evening before I arrived. After I explained that I didn't have internet access unless I was in a wifi zone, Volkan (who was really nice, otherwise!) asked me to call him when I arrive, which I had already explained that I couldn't do. The result was that I was standing in a dark stairway for 15 minutes before another guest kindly let me into the apartment to use the wifi to contact Volkan, after which I had to wait another 10 minutes for him to turn up.
When I arrived, I went to buy some food from the supermarket and put in my allocated cupboard (each room has its own shelf). When I came back later in the day, however, all of my food was gone. I suspected that it was the cleaners who assumed it was from a previous tenant and threw it away, but this was very frustrating as it meant that I had no food for breakfast the next morning (New Years Day), and I had to go and do my shopping all over again. Fortunately Camila & Paulo offered me a refund of the amount that I spend, which was very generous, but nonetheless this still should not have happened.
In the room itself there was no duvet, but only a thin blanket which was definitely not warm enough for the winter nights. When I asked Camila & Paulo if there was another blanket that I could use, they directed me to take one from a room that no one was staying in, but it had clearly not been washed after use from the previous occupant, so I opted to shiver through another night.
The bed itself also had a very pronounced dip in the middle which made it quite uncomfortable and the walls were quite thin so you could hear the other guests in the next room, but fortunately most of the guests were very nice.
Both of the showers were broken in different ways - one was not draining and in the other the showerhead had to be handheld.
Finally, the internet stopped working in my room halfway through my stay, which was annoying since I was trying to work from the apartment in the mornings.
Unfortunately, my stay in Camila & Paulo's apartment was my first (and hopefully last) negative Airbnb experience.
