Elena's place was in a very good location in a quiet neighbourhood, the metro lines 6, 8 and 10 were just a few mins walk away, as was the Eiffel tower. There is a very good korean restaurant and a supermarket just below the apartment. Amenities like washing machine, iron and tv were all present for a comfortable stay and the apartment was clean. Elena was swift in response.
However, be warned that the apartment has no lift and you may need to lug your luggage up a rather narrow flight of stairs. When checking in, if the housekeeper is to meet you, we had communication difficulties as she speaks almost zero English. also, the apartment is old and creaky and was quite difficult to move around due to space constraints. those with big luggages may find difficulty in places to put them. The furniture is old and prone to damage - fair warning given, you may want to take photos of the furniture if it has prior damage (as proof that you had not damaged it - I was asked to pay 70 euros for a scratched table that i was sure I had not scratched that badly). Overall, it was pleasant place for a short stay.
