In a great area of Paris with amazing food all around (including some awesome food options right in front of the building) and everything worth seeing within a reasonable distance - driving, or walking if you don't mind 20-30 min walks!
As for Nectar itself, the place is cozy but modern and we had a very comfortable stay. Be mindful that this is on the 3rd floor and the climb can be tough for the elderly (and those out of shape).
A lovely place but did get warm on warm days. A/C or better fans would have helped. La Marais is a lovely area. The service provided my Miguel was outstanding
