We did not get to meet Sarah and Pedro, but we checked in with their friend and had no problem. The flat is as shown in the picture, right in the old town, with many cafes and restaurants around in the history set.
Although we wish we’d known, to travel to the apartment is on the other side of the hill from the metro station arriving from the airport, it was quite the track to walk with suitcase. Other than that, the apartment is perfect for a couple of days stay.
