The location is unbelievably good - short walking distance to Les Halles metro & train station. Still, this was the first time that we didn’t use metro at all in Paris because we could walk everywhere. We checked in late and it was a little difficult to navigate through all the doors with different codes, but we got good instructions.
Only downside is that at least from the other bedroom you could hear the neighbours quite clearly and we were a little worried if they could hear us too.
