Elena is a great host. She responded to emails very fast, except for the time she has to look for answer to the question.
Self check in is very convenient and very simple.
Just a few steps to get keys. Just do not expect Elena to reveal the procedure of self check in earlier than just 3 days prior to arrival. I guess for safety, it is done at last minute.
Apartment is nice and big enough for 4 people.
Washroom and shower are the size appropriate for European country, smaller than in America.
Apartment is on 4th floor (American 5th), and floors are higher than we are used to. There is no elevator so you have to climb up. After day of walking around Paris this is the part of day you mostly do not like. But this is reality here, just get use to it, as it is part of the Parisian experience!
We recommend Elena very much.
