The studio is perfect for one (or max. two) person and in walking distance to the city center and other attractions. Word of advice if you come with heavy luggage: Use a taxi from the station to the studio (tell the driver to stop at Restaurante Velho Eurico) as you've to walk uphill with a lot of cobblestones stairs. Without any luggage is perfectly fine to go up and down. I felt very safe in the area.
