Michal and Lenka have a lovely apartment that was ample enough for the three of us. We were pleasantly surprised! It also comes with a washer which we appreciated. The apartment was also very very clean. Both were very communicative and extremely helpful when we had questions with the heating. They also sent out of their way to make it convenient for their guests with helpful tips to visit around Prague. The apartment is also nicely decorated though bedside tables would help for the bedroom. The TV even has English channels.
The only con was that we found the apartment a little far from the main centre of town. Not major, but something to consider. It is about ten minutes walk to the metro, plus another ten to the town. I would also advise against walking over the closest bridge as it is near a large highway and not a pleasant walk. There was also a noisy upstairs neighbor who woke us up with banging on the floor at 3am on Friday (which startled us a bit!), and then again on Saturday at the same time with more banging and music. Unfortunately, this left us quite tired the next day.
