To make it short - the apartment, location and host are awesome.

Lets get into detail:
The apartent is located extremly central, just 3 minutes by foot from metro station "Namestí Republiki". The apartment itself is within a small shopping mall with unique little stores like a very good butcher, but also a vegan store and a few other nice restaurants (don´t worry though, the mall is small and quiet). From 10 pm on the outside door is locked, so that only guests and owners are allowed to come in.

The apartment:
The aparment has 3 rooms: One bath, one hall and a large room with kitchen, bed eating- and living room in one. However, Josef told me that the sleeping room will soon be separated by a dry-wall. Both the bathroom and the larger living and sleeping room have nice big windows, which are providing a lot of daylight. However they are facing the inside of the building, so you don´t have to worry about privacy.

The beds (I slept on the couch while my friends slept on the bed) are very comfortable and large. The normal bed is easily large enough for 2 adults plus a small child. In general, Josef really didn´t made any shortcuts: He spend a lot of money on the interior and you really see that. The apartment has high quality wooden parquet, a custom made wall unit that goes accross from the living room into the kitchen and offers a lot of space to store your laundry and still looks awesome. The lightning is also very nice, its done with LED (?!) light-spots that are integrated into the ceiling, and two indivual lamps over the main table and besides the couch. The kitchen has - unlike other aparments in prague - enough cuttlery and dishes for 4-6 people and a dishwasher for your convenience.
The bathroom is another dream, oh my...black tiles and white washbasin that is integrated into a wooden stand, topped of by a bathtub...oh boy. Josef promised me he will upload some new pictures soon, but until then you might want to have a look at the pictures that I took, during my stay: http://bit.ly/1VGjtkZ

The "bonus":
Everyone who has travelled before with AirBnB knows: The host decides between make it or break it. And I can tell you, Josef is a winner. Even before the trip started he did everything possible to help us. He asked if he should organize a parking spot for us, he offered us a discount for entrance into a club during new years eve and another very good cafe for any day of our choice. Also he spoke very good english and provided us with all the information we needed, took the time to answer all of our questions and showed us the area around the apartment. He even supplied us with travelling guides about prague in our mother language (german)!

If you look for a great host and apartment - this is it!
