We had a great stay at Koro’s place.
Koro is a lovely woman. Warm, friendly, courteous, very helpful and informative. Always contactable. She was there on our arrival, and carried our bags up ( we are 3 sisters in our 70s, with bad backs!) and she arranged for someone to come and carry them down when we left. She gave us all the information we needed and we actually spent quite a lot of time chatting with her. She was so nice!
The flat is very good. Through a courtyard and very quiet. Bright and light and nicely furnished. The living room was spacious as was the upstairs bedroom, and the bathroom and kitchen were well equiped. Possibly the 2 downstairs bedrooms are better for children in a family. They are connected and there is only a toilet. The mattresses were particularly good and we all slept well.
For us, the only negative was that the closest metro was about a 15 minute walk, so we ended up taking a lot of taxis - which we liked, as it provided sightseeing opportunities! The area itself is lovely and we were surrounded by amenities including food shops as well as some good restaurants.
Altogether we had a great time in Paris and our accommodation certainly contributed.
