Loved staying here - walked into the centre in about 15/20 minutes and it's a nice walk too, passing a lot of coffee shops etc once you get to the river. Got cheap taxis back at night (about 3 GBP).
The place is very clean and was really spacious too - bigger than it looks in the photos! Great price for the stay.
Overall I'd definitely recommend, a lovely Airbnb for a couple or friends to stay in in Prague.
Only comment would be to bring your own shower gel as there was no toiletries in the Airbnb . :)
