Marianne was a very friendly host and responded immediately to all my questions. The flat is very well located, not far from the big interchange station "Kings Cross" and also easy to reach by bus. Unfortunately, the bathrooms were not always perfectly clean during our stay, which is probably due to the number of other guests using the bathroom. In addition, the house is not very soundproof, for which Marianne can of course do nothing, but it should be mentioned.
But all in all, we had a very nice stay.
