The flat is perfect. It had everything I needed, it was light, quiet, and in a great location. The landlord also explained how to control the heating. I was very happy with my stay.
There was a hidden mandatory 1000 CZK cleaning fee. It was communicated clearly before the contract signing (so I could have still changed my mind) and it was still a great deal with that extra 1000... but still...
The flat was very well equipped. It contained a fridge, microwave and a modern washing machine which were not mentioned in the description, it was a pleasant surprise. Would miss a writing/PC table if I did not have my own. There were more than enough sheets and towels.
The flat was not dirty but it was not super-clean either (which kinda contrasts with the mandatory extra fee). I had to re-wash some dishes and pots for example.
The location is really great. Right in the city centre, plenty of bars, pubs, restaurants, cafés and shops nearby. Great transport accesibility. If you are sensitive to noises of the night-life, beware this is not really quiet: there are plenty of drunkards under the windows every night. Still, it is located in a smaller street so for the city center it's actually pretty good.
The building is nice, with nice courtyard.
Recommended. For the price at the time it was great.
