Me and my girlfriend stayed in Prague for the weekend, not for the first time, we are both big fans of the city.
The apartment is definitely the best in Prague we've been to, it's very clean, quite central yet quiet, big enough for two people and all in all really nicely furnished. You can reach everything by foot.
František is an exceptional host, always replied within minutes, always friendly and helpful, it was an awesome experience.
If you're looking to stay in Prague and this apartement is still available get it! I cannot recommend it enough, safe to say that we'll be back :)
