Seriously fantastic find. Great location, air conditioning, a parking space, 4 beds and 4 bathrooms, 3 floors, a kitchen, linens, and easy check in/out. There is even an elevator in the building (after one set of stairs) for all that luggage.
Prague is beautiful and fun and there are restaurants everywhere! Sarah has an awesome guidebook waiting for you as well.
Book. It.
