The apartment is in an excellent central location, it's easy to walk to everywhere and Prague is a beautiful city. The hosts are located in an office on the ground floor of the building and were very friendly, communication was good as was the concierge. The apartment is a good size and was clean.
The kitchen, however, was a real let down, it looks fine in the photos but the equipment was woefully inadequate, there are no facilities to even make a cup of coffee. We did suggest that a cafetière would be a useful addition to one of the girls in the office but were told we should get take-out coffee from a café. The kitchen equipment may have been ok once but now it is just a mis-match of a few items including a pan lid that doesn't fit the pans and the lack of wine glasses is a shame.
It is quite noisy outside at night, although it is residential, there are quite a lot of drunken groups around at 2-3am, especially at the weekend.
It was not perfect but I would thoroughly recommend a week in Prague and you couldn't ask for a better location than this apartment.
