We stayed for several days over Christmas at Oliver and Lydia's place.
The communication with them was great, both before as well as during our stay there. They were nice and proposed us several restaurants in the area and things to do around London.
However, when we got to the place, the apartment was dirty and messy. The dishes and trays were sticky, the fridge was full of half-used stuff, the main window to the terrace was very dirty, and overall in the flat there was a strong smell from the sewer…So upon arrival, we had to do cleaning work... not great when you're starting Christmas holidays...
Another surprise was that, even though we booked the place for 4 people, we only had 2 towels. We raised this with Oliver, he apologised for it and he told us to pick up towels from another nearby residence they had. We had to do so, in the middle of the night and again, problem solved, but far from optimal.
All in all, nice people to interact with, but not on top of their place. Pity...
