Krystian and his guy did an excellent job fitting our kitchen; they were punctual, reliable and cleaned up immaculately at the end of every day. I trusted them to be in the house unaccompanied; they were very hard-working and well-organised (e.g. had most of materials needed at start of each day, not constantly having to go back and forth to suppliers for extra materials) and completed the job well within the estimated time, and to a high standard of workmanship.
Krystian is an honest, straight-talking guy with a dry sense of humour, so you may have your taste questioned along the way ;-)
