Kent's place was great! Exactly what it looks like in the listing, and very clean inside. Vivienne greeted us there and was so incredibly helpful with lots of tips about the city. Kent also arranged for a taxi to pick us up for our red eye departure flight, which was a lifesaver. The kitchen was well-equipped and we made ourselves a home cooked meal with ingredients from the supermarket that is within walking distance.
My only thing would be that the location of the apartment isn't super pretty, but we still felt safe for the most part. It's on the first floor, so the bedroom windows are right at street level, so we made sure not to speak English or identify ourselves as tourists while outside at night until we let ourselves in. There's graffiti everywhere, but that's how it is in most of Prague anyways. The huge upside to the location though, is that the bus stop is literally 10 steps away.
Overall, we loved staying here! The hosts were seriously just so accessible and helpful, and because of that, we felt very well taken care of.
