It's a great location and apartments to stay in Prague. The host is very polite, it was really easy to communicate and resolve any questions from our side.
Apartments are huge, clean, common areas are well maintained, and have great furniture, floor heating in all rooms. All kitchens are equipped extremely well, you will find there anything that you want!
There is only one controversial decision in apartments design: glass doors, especially for toilets and showers in common areas. So you will definitely know if anybody is taking a shower or sitting there right now through the hole between the glass door and glass walls...also it makes noise isolation poor.
Some furniture like beds need maintenance, it makes a lot of noise when you even just sit on it.
