Jan and Sarah's is a discovery that impresses you on first hit and grows on you the longer you stay there. Two blocks into the calm of a residential neighbourhood, it's still walking distance from all of the main attractions in Prague. The place is clean, bright, big (by European standards), and has everything you need. A couple of blocks in one direction are a series of trendy and bustling restaurants and bars. A couple of blocks in another direction are numerous boutiques and a gym. A couple of blocks in yet another direction are famed upscale restaurants. After walking the cobblestones for hours a day, it's great to come back to this place and its view of the river, put your feet up and know that an excellent dinner is only a couple of hundred meters away, be it hip and reasonable or high-end with stunning decor. I never met Sarah but Jan is bright-eyed, pleasant and extremely helpful. I paid for his offer to drive me in from the airport (rather than a cab). It was money well spent, and good conversation the whole way in. Jan was in touch almost daily, whether it was directing me on how to do things like buy soccer/football tickets or commenting on my comments about where I had a cocktail the night before. Can't imagine giving a higher recommendation.
