We've stayed in Paris a few times and had come to expect sub-par apartments with few amenities. Thuy's place is the total opposite and we were so pleasantly surprised!
The flat is a delight; high ceilings, heating, great shower. The bed's comfy and there are cute little touches everywhere. We were particularly impressed with the full suite of amenities in the bathroom and the fridge, which had enough for us to pretty much make breakfast with every day. Thuy and Franck were great, we're only sad we didn't have long enough to stay and have some drinks with them.
In an amazing area surrounded by bakeries, bars and killer restaurants, about 10-15 walk from Le Marais. Ignore the comments about the noise; I am a very light sleeper and with the exception of Saturday nights, which is a given pretty much anywhere, I slept like a dream.
