Had a great stay here; the place was very clean and well-kept and was right next to the metro (if you find the smaller entrance nearby).
The area along the main road is not one of the prettier parts of Paris; however if you go in the opposite direction towards the canal and walk along towards Stalingrad, you will find lots of great bars and restaurants - also a beautiful walk on a nice day.
One other point is that the apartment is quite small - one double bed and one sofa bed in the only room (excluding the bathroom and kitchen), perfect for a couple or two friends but no more than that.
Also there is a homeless man that sleeps outside the block of flats - he did not bother us but just something that is worth mentioning.
All in all, a great stay - especially if you are not looking to spend too much time at home and just want to use this as a pleasant place to crash.
