This is quite a good hotel for the price (usually at �70 per night but on Hotel Club website can get it for �39!) There is a lift but I don't know if they have rooms with a walk in shower but do have showers in the bath. You'd have to phone and ask.
If I can be of further help don't hesitiate to ask
I stayed at a wonderful hotel in Paris, rue duperre (pigalle metro station) near Moulin Rouge called Villa Royale, they have cheap deals and guess what?
The hotel rooms are all named after old movie and rock stars...very 'avant garde' and plush furnishings and right opposite the metro. Brill.
The rooms are all ensuite...we stayed in the Serge Gainsbourgh Suite...opposite the John Lennon!
