Really not suitable for four adults as the space is small and the sofa bed not suitable in our opinion for 2 adults. Location is great with easy access to restaurants including a sports bar at the top of the street with great burgers and excellent onion soup! Only about E10 for a cab to Eiffel Tower or E12 to Notre Dam or The Louvre. The lift capacity is 225kgs for 3 people max, so plan on walking the 5 storeys or waiting for the lift if your group is 4.
