We just had a great 3 night stay at Alzbeta's place. The apartment is stunning, modern and comfortable with everything you need. We found the instructions Alzbeta provides in the house manual to be really helpful and informative, she's great and replying promptly to any questions you may have.
The apartment location is great for public transport and links all around prague, however we found this area to be quite quiet even though it's in full season, the bars/restaurants close strangely early (11ish) so we stayed in town on most nights which then meant having to taxi back as the metro finishes at midnight, but the cost isn't too bad as it's not too far away, but you could also walk it which would take about 40 mins.
I would highly recommend Alzbeta's place for a stay in prague, she has really gone all out to make it special for her guests and it certainly delivers.
