Stop looking, you've found it! I recently stayed at the lovely Attic Hastalska in Old Town Square and had a perfect experience! We were a group of 6, two couples and two friends, and we had ample space to spread out and feel at home. The flat looks even better in person than it does in the photos. The Main bedroom has a king bed, flat screen TV, Large bathroom with a tub and stand up shower, and a very large closet that is left empty for guests and equipped with hangers, baskets, and an iron/ironing board. The 2nd bedroom has a king bed, and there is a half bathroom by the front door. We shared the shower/bath attached to the Main room. The 3rd upstairs bedroom has three single beds, and a full bathroom with a shower. The water pressure was great, air conditioning worked wonderfully, and the kitchen was stocked with everything one might need. As for the location, you can't beat it! Located right in Old Town Square, we were able to walk everywhere! I highly recommend grabbing a coffee and something to eat around the corner at The Bakeshop on Kozí. Everything was delicious! Rached was a wonderful host, and very easy to communicate with. He even set us up with transport to and from the airport, which made traveling a breeze! I will definitely stay here again on my next trip to Prague. I may even pick up a late and one of those brownies around the corner!
