For those short of time: These flats are terribly unclean and not fit for tourists unless the below is rectified.
These purposefully built flats are small and no more than what is needed for a long weekend stay. With that in mind -
1) The flat floor was very very unclean. I typically take my shoes off in the properties I stay in. I didn't on this occasion. The cleaners clearly hadn't bothered to mop the floor of what is a very small flat with a tiled easy to clean floor (if they had, they hadn't done a good enough job) and dirt was accumulating under my foot.
2) I realised on the last morning of my stay in the shower that I have been sharing the shower with small black worms. I have taken pictures and a video.
3) On arrival I went to pour myself a glass of water. As I was drinking, I saw that there was a lipstick mark from the previous tenant. I then went to wash the glass and then realised that I hadn't been left with any washing up liquid. In general, next to nothing is left in the flat in this regard.
4) The hot water in the shower typically only lasts for a minute and then the rest of the shower turns lukewarm to cold.
In summary, I do not recommend this flat to anyone unless they improve hygiene standards. It is a very small property which has probably been designed for airbnb guests, should be very easy to clean sufficiently and fell woefull short of expectations. I will be contacting airbnb about the small black worms.
