The apartment is as good as it looks in the pictures. The kitchen area is small, but is well equipped and has all you need to prepare light meals for breakfast and lunch. Everything you might need for your stay is provided, from a large range of guide books and leaflets about Prague to good stock of towels, shampoo and washing up liquid.
Gabriela & Michal were good hosts. They were there to meet us, even though we arrived 15 minutes early. Mainly they stayed out of our way, but answered questions quickly.
The apartment is on the 5th floor of a well maintained building with a lift, so there's little street noise. The location is very central. A lot of Prague's monuments can be walked to in 10 minutes or so and it's easy to get a tram or metro to further a field places. There's a large supermarket next door, so very easy to get supplies should you ever want to eat in the flat.
