This is a great value for its money. We had a great time staying in Nicola's appartment. Very quiet neighbourhood. However, sometimes you can hear the speakings of the neighbours of the next flat (only if they are speaking loudly).
Although it is quite far from the city center we had no problem because metro station is about 600m far away and a bus stop about 200m from where you can take the bus Nr. 87 to center.
Nicola was very helpful, because we arrived in the morning and he let us leave our luggage at the apartment until check-in time in the afternoon.
