Perfect location to experience Paris. Le Marais is stunning so plenty to do at night around the area. St Paul's Metro is just across the road and Bastille Station is just a few minutes walk (direct line to Gard du Nord which was great as we came via Eurostar). Le Louvre is also only a 20 minute walk.
We stayed on the hottest day of the year and the fans provided were a much needed bonus.
The only downside is there was no lift and I had read somewhere on the website that there was - which was difficult for my friend on crutches to climb the 4 flights of stairs.
All in all, I would use it again if I came with friends.
