I booked Regine's flat for a long weekend in Paris mid-Feb with my mum for her birthday. Coming in from Gare du Nord (Eurostar) the location was really easy and around 15 euros by taxi, or a few stops on the metro. It was a relief to see a lift so we could easily access the flat with our luggage.
The flat is everything it says in the description - and tidy, clean, minimalist. The 'room with a view' (living room) was lovely as it backs on to a large courtyard with a huge graffiti mural painted across the wall - I loved this! Another luxury was access to a nice bath with unlimited hot water. Walking to Isle St Louis was about 25 mins and en route there are so many lovely shops, restaurants nearby. We found one, 'Café Charlot' on the last night, which was kind of French Brasserie, meets New York, meets Paris again! Serves food all day and great quality/atmosphere.
Would highly recommend Regine's flat for location and comfort.
