This is a fantastically well designed apartment. The use of space is astonishing - as are the views. However, there are flaws.
The level of cleanliness was not up to the standard of the property. The kettle and sink area were mucky but, worst of all, the headboard and mattress were extremely grubby and stained.
We had considerable disturbances from noise during our stay. There is a commercial shoe workshop in the building with constant mechanical hammering noises through the week. This woke us up at just past 6am in the morning. On the Friday evening the bar next door (which the hot tub and terrace overlooks) had a live 'trash party' blaring heavy metal until 4am.
The host is very efficient with communication but I don't appreciate being patronised and told what other guests think or that 'city noise' is acceptable. This isn't city noise - it's constant and incredibly intrusive. We refunded one night of our stay - this is somehow meant to be seen as compensation for a totally ruined trip. We were refunded after leaving a day early to find alternative accommodation where we could actually enjoy some sleep.
This could be an incredible place but I would urge the host to be much more up front about some of the conditions around noise and particularly around cleaning.
