Karin is an excellent host, very friendly and helpful.
The apartment is fantastic. 3 minutes walk away from the Arc de Triomphe, so very central. Great for Rer/trains from airports, close to bus station at Porte Maillot also. The apartment is very clean and bright, with everything you will need for a holiday, bed and settee are very comfortable, and the shower is excellent - also all extremely clean, which is everyones' wish.
The apartment is on 6th floor - has 2 lifts available. Very bright and sunny space overlooking a large central garden, so also wonderfully quiet at night.
I would highly recommend Karin and her apartment, and will definitely try to stay again on my next visit to Paris.
