The Location is incredible! You can easily get all historical places, famous restaurants, stores and vivid night life — everything in a walking distance (~ 3km max). In addition, there is a park nearby where we walked every day. The district is peaceful and safe.
Move on to the host. David is one of the best host I've ever met! He met me in the flat and told how to use equipment and other general rules. During our staying he was ready to help very quickly if smth happened.
About the flat. It is well equipped: coffee mashing, washing mashing, fan, soap, papers, bags — you can not worry about anything except food :) There is only 1 drawback — no windows, if you are going to stay long you have to be prepared to the absence of sunlight.
I'd highly recommend this place and hope, that I will come back in the future.
