Nice little apartment in Bastille, very close to line 1. Very cozy and under the roofs.
Keep in mind that the flat is on the 6th floor; if you are "not more" young or a bit "off shape", it could be a bit fatiguing. If you are like me (I am 50, but I live on 4th floor without elevator), all is fine.
There is everything in the flat for a short stay, all equipped, microwave, shower, tea and coffee...all nice and clean.
The flat is used by the owner, so keep it in mind (there a few cupboards locked for privacy), not everything could be used by guests, I think.
There is not TV (I have no TV in my home, so for me it's a plus!), but, in Paris, if you need TV to pass your days, there is something wrong with you!
Saturday evening is a bit noisy (but hey, Paris is Paris!) but on the 6th floor the noise is actually far, I slept well. The other days are perfectly fine.
All considered, a nice stay.
