Despite being a pretty good renovation of a well-located apartment in Campo de Ourique, I had so many problems trying to enter the unit.
First, they sent me the key pick up instructions after the check-in time, so I had the keep asking about where/how to pick up the keys. Then, arriving at the unit, it was impossible to open the gate that leads to the courtyard and I had to wait for 2 hours outside in a rainy night until we could enter.
Next day we spent all day basically locked in because we were afraid of leaving the place and getting locked out again. The host promised solving the issue next day but never did.
In short: I paid for 2 nights, spent 1 night waiting in the rain and the next locked in because the host was incapable (or not interested) of getting us working keys.
FYI: The problem WAS in the keys, we checked with a person who lives in the vila and his keys worked fine.
