This unit is quite well-located. I've stayed in the Smichov area for my last 4-5 visits because it has so much in the area (e.g., groceries, shopping, restaurants, cinema, transport) and its proximity to the center is excellent. Despite all of the goings-on in the area, this unit is very quiet because it faces an inner courtyard. The downside is that the courtyard houses a parking lot and the garbage/recycling bins. I cannot say I loved looking out and would recommend blinds for the main room (this would help with the summer heat as well).
The unit is clean and modern, with an especially nice bathroom. However, it is quite small and thus, not ideal for a stay of more than a few days.
I did stay three weeks and found the sparse kitchen (e.g., no colander for draining pasta), lacking closets/storage and the tiny washer to be quite limiting. The washer is VERY small (holds approximately 5 items) and the drying rack can hold a shirt or two (I ended up purchasing a larger one). Ultimately, I ended up doing a lot of loads to get all of my clothes clean. Moreover, there are no actual closets or dressers, just a couple of short hanging bars where one can hang a few items. Again, this is suitable for a short stay but not for more than that.
Ultimately, a decent place for a short-term stay.
