I can't say enough good things about Carlo and his place. We loved our stay. The apt is in a very nice building (with elevator and friendly doorman) and a communal garden. Well appointed space filled with design, photography and fashion books. There is even a piano, which Carlo so kindly had someone tune for us. Bathroom has nice toiletries (Aesop) and shower has good water pressure. Sheets and bed are very comfortable. It's like staying in a hotel. Kitchen was stocked with the essentials and some extra items like pasta, condiments, etc. He also has a booklet filled with recommendations on where to eat and grocery shop around the neighborhood.
Now, about Carlo. He's is one of the nicest people I've had the pleasure of meeting and so is his colleague, who helped us check out while Carlo was out of town. Great communication before and during our stay. Very accommodating and thoughtful. We stayed for 3 weeks, so he also arranged for a cleaner to come help change sheets, towels etc (only 10EUR). Also left us breakfast, a bottle of wine, plus snacks.
Would highly recommend Carlo's apt!
