Krzysztof's place was absolutely amazing it was so modern and spacious and probably one of the best apartments we had stayed in whilst travelling around Europe it had a huge kitchen and living area with a great bathroom and bedroom. The location was also fantastic super close to everything in a safe neighbour hood very close to transport (the underground) which was two stops to the heart of the city. Whilst we there though it was very hot and there was no air conditioning so it was quiet an uncomfy nights sleep we did have the windows open but as there is a bar across the street it was quiet loud (however we did stay there on a fri and sat night) also if you like your sleep ins then you may not get them here as there are no block out blinds so when the sun comes out your awake.
I loved this place and would stay here again.
