This studio is a gem if you're traveling alone or as a pair. It's equipped with everything you need (bed, shower, toilet, washer and drying rack, iron and ironing board, fast wifi) for a great price. Prague is a very touristy city, especially in the summer, so being just out of the old town and city center was a refreshing way to get away from the huge tour groups, whining kids, and loud weekenders. The Dejvická neighborhood is pleasant and full of good, cheap bistros and restaurants. It's an easy metro ride to the old town square and Charles Bridge and a walkable distance to the castle. If you like walking, as I do, it's very doable to not use public transportation at all--one day, I ended up walking all the way back from the old town without even meaning to.
The host is fantastic: he greeted me at the apartment on the day of my arrival, gave me a guide and city map, and recommended some of his favorite places.
Overall, this is a great place to stay I Prague. I highly recommend it; I think it's an ideal combination of convenience, value, and authentic experience.
