I can just recommand this place! We got welcomed very friendly and we got a lot of informations and tipps what we could visit in prague. They have been very flexible with our time of arriving.
The place is very nice. It is very clean and it has everything you will need for your stay. Your not that far from the center and the train station is in front of the building.
If you're planning to be in prague for a few days, this is the perfect apartment.
