We have been staying in Katia's flat over new years eve and we cannot find a negative comment about it! Very nice building and super central location, very spacious flat with amazing wooden floor and large rooms. Everything was also extremely tidy and clean- towels and linen like in the hotels and fully equipped kitchen.
Definetly would come back and recommend this to anyone!

Also, Katia is extremely friendly and nice and has been a pleaasure to meet her!!
