The flat lacked a basic level of cleanliness. The bed was made nicely for our arrival with cute little gifts, but the floor had not been cleaned and was covered in crumbs and grime. We weren't comfortable going into the bathroom without laying something on the floor or walking around without slippers. We generally found the flat to be fit for purpose, even if the fixtures were dated, so it would've been fine had it been cleaned properly.
The apartment is in a good location near Chalk Farm, Belsize Park, and Kentish Town, but the estate it's in doesn't feel very safe. We know it is not the owner's fault though.
Charlotte was very responsive to our messages so that was very appreciated.
London is expensive but renting the apartment for a relatively cheaper price (but still high) doesn’t justify not fulfilling the basics. The place may be a good budget option for travelers to London if the cleanliness is sorted out. We were pretty disappointed considering the price.
