The apartment is really great and worth money that we pay for it. Close to the Eifel tower, I think no more than 5 minutes walk ;) Very often we start our day from the short romantic walk near the tower. Very close to the subway station, other alternative - to take a Sienna cruise from Eifel tower. Location is perfect as for me. You can easily reach all main Paris attractions.
Photos corresponds to the reality :) Usually an apartment looks better on photos, but in this case it exceeded our expectations) Apartment is beautiful, cozy, we'll equiped and suits well for 1 or 2 persons.
Unfortunately we did not meet Diogo personally, but he provide very detailed instructions, so we easily got the destination.
Highly recommend apartment and owner!
