Overall this is a great place to stay! Very close to many things in Prague- excellent food on the street, and spacious living/sleeping area.
I would recommend getting exact directions from however you will arrive (plane, train, bus, metro) we were very lost and it took us over an hour to figure out where to go. Once we found it we were fine- but the directions weren't the smoothest for us.
There was a coffee maker, but you will need your own coffee and the washer and drying rack were a luxury! Especially with a toddler!
