The flat was really "small and cozy" as described. For two persons and a few days of staying there, it's totally enough and everything you need is there. Walking into the center is not very comfortable (30 min), but a bus station is just next door.
Altough the building is very old and ugly, the flat itself looked rennovated and very new. Also everything was clean and practicable to use.
The communication to Veronika worked very well and she provided all the basic things you need for a short stay (towels, toiletpaper, etc.).
All in all I would definetely recommend this flat.
