We were using this airbnb as a base for a family city break. The apartment is large, bright and spacious - it is very well located for Wenceslas square and all of the central Prague tourist sights, plus it has good transport links. It was clean and all of the facilities worked fine. It was helpful to have a washing machine in the apartment also. The hosts were very responsive and helped introduced us to a reliable, fair and friendly taxi driver who did our airport transfers. In advance of the trip, we were sent a google map with lots of useful info marked on it.
On arrival, seeing the graffiti on the door to the apartment block was slightly off-putting. Also, the apartment is on the corner of a side road and a 3 lane main road that was very busy and made it noisy at night for those sleeping at the front of the apartment (it was hot there, so we had to leave the windows open). There seemed to be a hostel next door/close by and there were people hanging around on the street making noise late into the night - on one night we were woken up by a bottle being broken beneath our window (note - we were on the first floor).
In summary, I think the apartment was described well, but I don't recall the description of the location. Ultimately it was well located but noisy.
