Absolutely great, adorable place. Very tiny, but stylish and convenient.
The bed on the mezzanine is GIGANTIC and very comfy. The balcony goes out on the backyard with a direct view on the Maiselova synagogue. It is quiet, not noisy at all, even though it truly is Smack in the Center. We were worried that it would be too hot on the mezzanine, but we were wrong - it was very comfortable. There are two sconces and two power sockets above the bed, so it's easy to plug in your phone or a comp for the night. There's an iron, a hair dryer, a little fridge. Frantisek is a great host and I suggest you follow some of his tips for eating out - they proved right on the money.
