This is a delightful apartment that I thoroughly recommend, and hope to return to one day. It's spacious, comfortable for two, well-appointed and must be one of the quietest apartments in Paris, which is amazing given its location. It is indeed in the heart of the Marais, although not the glitzy expensive heart, which is a 10 minute walk away. Catherine was an excellent host and the arrangements for access were all smooth. The apartment is on the first floor, so not many stairs to climb.
