I didn't get the chance to meet Florian but he was very responsive and helpful. His flatmate was also super chill and very welcoming.
Bed sheets and towels were ready when we arrived and everything had been cleaned.
The location of the flat is particularly practical: close to the city center and very well connected by bus and underground, even though the neighborhood isn't the best.
Overall, I would recommend this place, perfect for a weekend spent exploring London.
