Mercedes has a really beautiful apartment. Our only feedback was that the check in experience was not as smooth as we desired. As we were not allowed to check in earlier, Mercedes suggested a luggage locker company within the city. However, the opening hours details provided was inaccurate so we made a futile attempt to drag our luggages there and walked away fruitlessly. In the end, we managed to put our luggage at Santa Justa train station which is cheaper and closes at later hours.
