The Instabook feature worked perfectly. When we arrived, Pete was there to welcome us. He clearly explained the rules and waited for us while we checked the apartment. Everything was laid out beautifully, from towels to bedding. Everything was clean including the washroom (very important!). Pete then took some time to explain to us where to go, where to eat, what to do and where all the major attractions are. He marked everything on a map that he provided, which helped us out big time. The free wifi worked perfectly. And the temperature control was regulated properly and easy-to-use. The location is perfect: a stone's throw away from Winceslas Square and the Old Town Square. The apartment in its entirety made our holiday a great experience. Highly recommend this apartment to families with kids and to couples or even young friends.
