Everyting was fine and as we agreed. Location is perfect, not to noisy - only thing that was a bit bothering was the smell of cooking from neigbouring apartments when windows were open, but - since we were mostly outside - it was just minor inconvenience.
Apartment is spacious, clean, pretty much with basic equipment, but serves its purpose. There are 3 separate rooms (one with 2 beds) and one bed in the living area, so it's comfortable for larger groups. Beware that the elevator in the building is very small, so if you carry lots of bagagge you must lift it one big suitcase at a time.
Metro station is close, and there is a cafe/bakery next to the building that serves good coffee and breakfast food, great for starting the day.
Roberta was expecting us at agreed time, provided us with some useful informations and did her part very well.
Overall, good experience.
