We stayed in another place in Lisboa before changing into Alex‘s flat. We called him to ask if we could enter the flat earlier than 3 pm. We were told that this is not possible as the flat was still cleaned shortly before 3 pm. When we arrived, the flat was unfortunately not cleaned at all after the stay of previous guests. This forced us to change our plans accordingly and that was very tiring. After it was cleaned it was not as tidy and clean as expected. However, the communication with Alex was good and he apologized and said that this is an exception. This may be the case but I personally wouldn’t recommend to stay there.
