We had a nice stay in this apartment in the summertime. The apartment is small and fairly dated, but cosy and big enough for 2 people (4 people would be very squashed). The shower was very good. The kitchen is fine for basic meals, and the balcony was lovely. Guests should note that bed sheets and towels aren't included in the price and cost an additional €20 from the concierge. There is free underground parking for one car.
The instructions for finding the apartment were not great, and the concierge does not speak any English which made finding and checking in a bit difficult for us. But Stefania herself was very responsive on the phone to sort these issues.
Overall though we would recommend this apartment.
