We had a thoroughly enjoyable stay in Simo's apartment in the Latin Quarter - it must be close to being in the perfect location for a visit to Paris. The apartment itself is small, as you'd expect in this part of the city, but has all the essentials necessary for 2 people. The street is very quiet, although we were there in August when the Parisians all go on holiday, so it might be different at other times. There are plenty of restaurants, bars, cafés, book shops etc. within a couple of minutes' walk.
