I stayed at Nina's place for several weeks and thoroughly enjoyed it. Location-wise, it is a few minutes' walk from Chalk Farm station, which connects directly to key stations like Bank, Waterloo and King's Cross St Pancras via the Northern line. Lively Camden is walking distance from the house.
Nina is a superb host. She makes it her top priority to ensure that your stay is as comfortable as possible. She is friendly but equally importantly, respects your privacy.
Her home feels like a proper home. It is very well-maintained and stocked. The room in the ad feels welcoming. If you enjoy cooking or watching films, you will particularly like the home as the kitchen is nice and there are tons of DVDs around!
To have your own private bathroom in a nice house with an excellent host in a fairly central location, I felt it was good value for money. Overall, I would highly recommend it.
