I stayed with my family in the spring at Casa Cosi for a week and it was a great stay.
The apartment's location is excellent, close to the main attractions of the city but in a quieter neighborhood.
The apartment corresponds exactly to the photos in the ad.
We had problems with noise at dawn coming from neighboring apartments on the first two nights, but after we communicated with the renter it was resolved. Communication with him is very fast and efficient. The apartment is located on the ground floor behind the concierge at the back of the building, it is very well decorated and equipped but in winter the bathroom and pantry/kitchen can get very cold.
There are no windows in the apartment, ventilation and lighting comes from a skylight in the pantry/kitchen.
For us this was not a problem, we just miss blackouts in the rooms to close the windows which are all high up and interconnected.
I recommend Casa Cosi as a great accommodation option for a group of four people.
