Central place but too much traffic in front of the house and too loud because of the student's rituals at the fountain at night (for Harry-Potter-Fans a place to be, also very close to the Livraria Lello! ).
Very narrow entrance and very steep stairs to come in (luggage could be a problem).
You'll get a big key to lock the door (it remains to a castle).
Furnishing was good, nothing was missing.
Heating (one on each floor) works, we needed both in March.
