The place is very well located and the view is breathtaking. You will enjoy watching the Eiffel Tower twinkle each evening. The accommodations are a fine size for one person (or for a couple that plans to be out much of the day). Had everything I needed for a one-week stay. Eric is a very responsive and flexible host. Very easy check-in and check-out.
A few notes for travellers - I won't call them cons as each person has their own sensitivities: If you are sensitive to light, you will want a sleep mask. If you have seasonal allergies, consider that there is a large plane tree (highly allergenic) outside the window. If you are sensitive to noise or prone to make a lot of noise yourself, note that as with many Parisian buildings you can hear the neighbors but for the most part they respected evening quiet hours.
