We called Susana before our trip and she was really kind and welcoming. She helped us with info how to get to the flat from the train station. We had some troubles in Portugal (our luggage was stolen from our rented car), so we arrived a day later and quite late at night, but Susana was very understanding and flexible.
She lives upstairs, so she let us in and showed us around. She even ordered a taxi for us for our departure.
The flat was as it looked on the pictures and matched the description. It was clean and well equipped. Maybe a bit too loud at night (there's a park under the windows), but I didn't have problems with sleeping. It was a nice experience.
