This apartment is charming and has retro furniture with some modern amenities to make for a comfortable stay. The location is about 30-min walk to the old town square, which is great for some respite from all the tourists. It's a stone's throw away from Naplavka where you'll find a wonderful farmer's market on Saturday morning and a food market that runs till the evening with wine and great local food. It is close to public transportation and not far from Charles Square, making it convenient to explore the new town on foot. From there it is also easy to get to the old castle Vysehrad where you can spend a few hours away from the crowds with excellent views of Prague and the river. There are some restaurants (including a vegan cafe) and bars close by.
One thing to note is that the apartment is on the fourth floor and there's no elevator so be prepared to lug your baggage up. The bathroom is separate from the toilet and does not have a real door. These were not big issues for me and my stay was generally good except for the noise from the heater that unfortunately kept me up all night. I think you'll get a taste of local life in this apartment and I'll recommend it for that.
