The apartment itself was perfect. It is actually a fair bit bigger than it looks in the pictures which was a nice surprise.
The kitchen is well outfitted though we didn't use it much because of the amazing places to eat out on Prague! The bed was comfy and the bathroom was clean with a good shower.
In terms of location it was about 40 mins walk from the old town and a 5-7 min ride on the metro. The metro station is literally around the corner so I would advise using it!
There is also a shopping centre nearby with a supermarket on the bottom floor if you need supplies.
If you're staying in Prague for a few days and want a nice stylish place to base yourself from I would certainly recommend this one!
