Don't know much about other alternatives, though this one is considerally one of the worst hotels i have stayed at. However, the location is quite central and there are good communications from the crossing of montmarte/lafayette boulevards.
Our room was not a pleasant suprise - the opposite.
it smelled a lot like - and you could definetely see - moissy areas.
Additionally, if you find better options - i may argue they would be more preferable!

Most of what is relevant has already been articulated - yes, the elevator is small.
I got in at the last minute for €110.00/night, and had it not been at the last minute I certainly wouldn't pay this for a 2* which quite removed from the downtown. It is also situated across the street from a city bus depot: and although I was on the third floor, the noise is definately an issue. Unless of course you close the balcony doors, which you won't do in the summer as there is no airco. It's located 1km from the RER which is acceptable, the area doesn't seem that bad and as mentioned, there are several markets available. The two gentlemen who worked the front desk while I was there seemed courteous enough and since I am a frequent Paris visitor, didn't have to call upon them for guidance.
However, when I initially entered my room - which seemed clean enough - I just threw my bags in and headed to the street. Upon my return later that night I opened the bathroom door and was met with a smell that was akin to a French truckstop urinal. And it stayed. The next moring, I awoke to discover NO toilet tissue and a previously used towel in the shower.
I have no idea if this was simply bad luck on my part, but am mentioning this for if there are others writing the same problem, we have a pattern.

This hotel is nothing fancy but for location, you can't beat it! Metro is minutes away, steps from one of the main streets. Breakfast included - croissant, baguette, coffee, juice, yogurt - tasty!

Free wi-fi in the lobby and on occasion, in the room. Very tight quarters - don't expect space - especially in the washroom. Stand-up shower only and very tight. Bring toiletries and wash cloth.

Beds were clean and room was done up daily.

The pictures that the hotel is advertising itself with are exaggarated! Some design elements are installed but altogether the rooms are not renovated, the bathroom was in pretty bad condition. The room was quite small as well. However, as we stayed in the city all day, it was ok for one night with a moderate price via booking.com.
