We really enjoyed our time in Prague and the apartment was ok. You can get the tram into town from the top of the road, number 9, tickets are purchased from some mini markets, seems hit and miss, which ones.
The apartment was ok for our needs. We have made some suggestions to improve cleanliness, so hopefully this is improved for your stay.
If you are a light sleeper and need rooms to be dark and quiet this apartment is not for you. We were awake at sunrise every morning, as there is very insufficient window coverage, due to the design. Also, the bed is directly above the lift shaft, so you hear 'bing-bong' every now and then at all hours.
The apartment is bright and airy and has great views. We quite liked the fact that we woke up naturally by the sunrise, however we wake up early anyway and don't really go out drinking, so it suited us.
Please do not be put off by my review, I am trying to be honest about the facts. Overall the apartment is nice and has good potential.
