Pluses—location is very central. We walked to the Louvre, Le Marais, the Left Bank, Montmarte. The Metro is a block away. We also loved exploring the arcades that are a couple of doors down with restaurants and small businesses and the grand boulevards. There are 4 cafes spitting distance. The place itself is clean and comfortable and definitely roomy enough for 4. We didn’t really use the kitchen but the bathroom facilities were quite nice.
Minuses: location. The cafes are quite lively until wee hours of the morning. Once we figured out how to properly close the windows we were able to block out the noise but we were there during a heat wave and without air conditioning it was stifling inside.
