The apartment is in a very good central location. Everything (Eiffel, Louvre, NotreDame, Montmartre) is within 10-20 min walk. Also lots of good restaurants and cafes, stores downstairs.
Apartment itself is very small - as EVERY apartment in this old part of Paris. The main concern is - STAIRS. Apartment is on the 5th floor and stairs are very tiny and narrow.
Otherwise apartment was clean, fresh, with all kitchen equipment, accessories, towels, pillows etc.
The host was friendly and helpful, waited for us to arrive late and gave us lots of useful information while visiting Paris, speaks good English and quickly replies to emails.
Overall experience was great!
