A really nice apartment with history in a quiet building and in the absolutely right place for lots of sight seeing.
Nice restaurants and cafes all around, and if you get tired in you feet, head and leg, it's cheap to grab a taxi - and just say 'Castelo / the castle' instead of the street name. Bus 737 just outside the house is also good to know.
If winter, buy nice slippers in the shops with wool products 😁
