The apartment was clean. We stayed there for 2 nights and used the apartment just for sleeping and preparing cold breakfast, so we didn't cook there and we don't have any comment about it but there was a clean electric cooktop for cooking.
The place is about 20 - 25 mins walk to the old town and touristic areas. It was very ok for us to walk from there to touristic places and we didn't use any transportation in those 2 days.
It was only me and my husband (2 persons) but according to there were two bedrooms with a double bed in each one, two bath and toilet facilities, we think the apartment is good even for 4 persons.
