I stayed at Bertrand's apartment with 3 friends for a week in March. We had a lovely visit and I would recommend this place to others. Check in was easy and the host was very friendly and accommodating even with our delayed arrival. The apartment was spacious for a one bedroom (with pull out couch) and we all slept comfortably.
The bath and toilet are in separate rooms, both with sinks and mirrors, which was helpful for getting ready quickly in the mornings. All of the listed amenities were accurate and the apartment was clean. The host provided towels, and there was coffee and tea stocked in the kitchen, which went well with our produce from the local Bastille market and bread from the bakery a couple doors down!
Regarding location, the apartment is very close to the metro and there is also a taxi stand out front which was helpful for when we left to go to the airport. There are many cafes and bakeries in the direct area and it is just a few blocks to the heart of the Marais. It is a longer walk to many of the main attractions, but there are plenty of options for public transportation and it's also an enjoyable, beautiful walk in any direction.
Thanks again, Bertrand!
