Our stay at Siep's beautiful, light, central and spacious flat was 10 our of 10. Siep and the flat delivered exactly 'as it said on the tin'.
Short, brief and to the point 'hand over' with very generous flexibility of check-in and -out times.
Having lived in A'dam for 8 years (albeit 30 years ago!) there was no need for much help, but I am certain Siep would have been there if necessary.
I/we might be back in the autumn.
