Daniel and Bea were pleasant and helpful hosts. The apartment was well-provided for, with everything a first-time visitor could need (bus schedules, maps, tourist guidebooks)! The place was large, comfortable, and modern, with a sound system and flatscreen TV. The shower did tend to leak if the shower curtain wasn't made to form an airtight seal around the sides of the tub, but it wasn't a big deal.
Location-wise, the apartment is right around the corner from the train station (fantastic!) and about a 10-minute walk from Wenceslas Square and 15 minutes from Old Town Square. It's a bit further away from Prague Castle and Mala Strana (perhaps 30 minutes), but the entire area is extremely walkable if you aren't on a tight schedule. Alternatively, public transportation in Prague is absolutely wonderful (though the ticket vendors and verification system is a little less intuitive, so make sure to read the helpfully provided transportation guides). Since the Old Town is so close by, it's easy to spend a lot of time wandering about that rather touristy area--but do try your best to explore outside of that, as Prague has so much more to offer! The apartment itself is located right outside of the main hustle and bustle, which was rather pleasant in my opinion.
Overall a great stay, and recommended!
