Had a short stay in the old town area of Porvoo and accommodated in Hotel Pariisin Ville. The hotel is very cozy and the service is excellent! Breakfast is rather compact but very good! There is parking place in the inner yard.
"Ground floor seems better; no elevator and breakfast is upstairs next to rooms."
"If you are a light sleeper, ask for a room on the second floor. First floor rooms face the street."
