The studio apartment is at a great location very close to the Eiffel and public transport. Apartment is a decent size for 2 people with a washer too. There is a small kitchenette. It is 6 floors up, but I guess that is the Parisian way of life ! You definitely feel like you are living like a Parisian.
Our host was incredibly kind and generous - she spoke to us about things we could do - helped us with places we could go to - we forgot to pack a bath towel so she provided us with one. We loved her generosity and would recommend you stay with her in Paris!
