What a gem -- the place and the hosts.
Martin and Tam are wonderful. They shared recommendations, were warm and flexible, communicated tremendously well from start to finish.
The apartment is amazing. Spacious 3 bedrooms. Amazing light and view of the park. Very high quality throughout, even the little things -- windows (quiet, clear, large), utensils and dishes, appliances, coffee maker, furniture, everything.
The building is great. Safe entrance. Small lift but still helpful for furniture. Very clean and high quality. Well lit.
The location needless to say is amazing. Having stayed in different neighborhoods, Le Marais feels a bit higher quality than many other popular neighborhoods. Less noise, cleaner, sophisticated, also feels safer. And there's so much right nearby -- farmers market, Picasso museum, etc.
In short: amazing. The experience actually exceeded our expectations (despite the fact that we already had high expectations!).
