Niko was a good host; was quick with communication and was at the property at the arranged time, and the property was clean (although these are minimum standards).
However, if you wish to be a responsible traveller then I do not recommend you stay at the accommodation. The property is more accurately described as a hostel. There is three bedrooms in the house which are all rented to Airbnb guests. The night we stayed eight people shared one bathroom. Our room was once the kitchen/living area. The hosts had installed a false wall in what was formerly the kitchen/living area to squeeze in another two beds. There was no external window. Window in the room opened onto the kitchen which then opened out to an external window. Privacy is limited and it is very hot/humid.
It may seem well priced but Prague public transport is very efficient and so you would be able to stay a little further out for the same price and in return be staying in a better property - we wished we had done this.
