We had a nice stay at Ali's place because of its excellent location and a comfortable and practical bedroom.
However, there were some problems regarding cleanliness issues. Both toilets (ladies' and men's) were stucked with dirt and bad smells, trying to use it was terribly disgusting. In addition, towels weren't changed during our stay and there was no toilet paper.
Moreover, the other guests didn't clean their dishes in spite of the posters on the wall asking each one to wash the dishes he uses. Consequently, when we wanted to cook anything, we had to clean dishes soiled by others, it was disgusting!
To conclude, this place is suitable for a couple who wish to stay in the real centre of London with a tight budget during no more than three nights.
