Unfortunately the cleanliness of the flat was a major issue as the cleaner did not clean it properly before. Also the equipment of the kitchen like pots and pans were so disgusting and wore out that we had to buy new ones. Everything was really sticky and the bed linen had to be washed before they could be used first and there were even some moths we had to get rid of.
Our host Jordy was very responding and supportive and sorry about that and sent someone for the bathroom and a cleaner again. However I still think even with all the cleaning we did ourselves (staying there 2 months) the flat needs a proper cleaning and some new equipment and proper windows.
Otherwise the flat is a ideal base for Boston - 2 minutes to red line and some nice restaurants in the area.
Also Jordy himself was very easy to communicate with and tried to help as soon as he was aware of the status of the flat so thanks for this.
