Costanza is the perfect host- wonderful check in with attention to detail and a fully equipped flat that ensured you had everything you needed. The flat was beautifully furnished and empeccably clean. The location is perfect- easy walking distance to all the main attractions. We had a 2 year old and a 4 year old- one of the rooms had a lovely single bed - perfect for our older child and a brilliant cot for our toddler who also had his own room. My husband and I managed to sit out on the balcony of an evening and listen to opera from the church next door- it was unbelievable! Look no further for the perfect flat in this amazing city.
