Marianne is an incredible host and you can expect to have any issue resolved as soon as possible.
The room was clean and comfortable and in a great location. (It's only a 14 minute walk from Kings Cross Station and it has some nearby parks if you fancy going for a walk.)
It is worth mentioning two things. First, this is shared house with 4 other rooms, so be prepared to have to wait to use the kitchen and bathroom. The fridge was a bit small and we struggle a bit to fit our food, but everything else was fine.
Second, this room is at the front of the house, so it is actually connected to the front door. During our stay we had delivery people knocking on the door multiple times, so just be aware that this might happen.
Apart from these issues, there's not much else to point out! It is a lovely room, well worth the price you pay.
