This studio is a great value for this central location. As others have mentioned, the WiFi is weak, the tram makes noise and shakes the home, the ladder and loft are annoying (even by Airbnb standards) - but you have all you need in a great location for a solid price.
Go get breakfast at Tartine and see Rubens for free at Saint Carolus Borromeus Church - on the same block as this studio!
