The apartment was big enough for 3 adults and 2 young kids. The prime location made it easy walks (30 min or less) to every major attraction however most things were much closer. Many restaurants right outside your front door made it easy to get a great dinner after a tiring day of being tourists.
The apartment was as advertised. There are great recommendations in their book, including for taxis with kid seats and various attractions and restaurants. They also had a crib available (just make sure to ask before checkin). The sun room was a nice spot to relax. Kitchen accessories were a little sparse. Overall it was a perfect place for a family vacation.
