Ivan's place is in the heart of Paris and walking distance to many tourist attractions. The amenities are great (good AC in the bedroom, great bath, nespresso machine).
However, there was loud construction during our stay, both in the street directly below us and on the building. It was difficult to be in the apartment during the day because of the noise, and we were woken early (8am-9am).
Overall it was a 3.5 star stay with the potential to be a 4-5 star place, but we were disappointed.
