Just impeccable settings. You can't beat that. The apartment is on the third floor without lift, so you might have trouble if you have big luggage, but Jana was nice enough to hold one end of my luggage to carry it that damn three flights of stare.
One neighbor from downstairs were not so nice to us. I was told the older Czech people are mistrusting to foreigners, especially if you are brown. We were coming down, and she purposely locked the steel door in front of us and said something in Czech. We were extremely courteous and tried to ask her if anything is wrong. She just shrugged and walked away.
But, its a lovely apartment and a great location. If you can cope with subtle Czech racism and three flights of stairs...this is a great place.
