in short: neat, rather calm, direct entrance from the street into the studio; in detail:
situated on a side street in the lively 10th district, the walking distance to Gare de l'Est is less than 10 min, there are 3 métro stations within 5 min (Château d'Eau, Strasbourg-St. Denis, Jacques Bonsergent) and a couple of bus lines round the corner on bd Magenta, plenty of cafés, restaurants and shops nearby.
the studio itself is a converted office on the ground floor, the entrance has a (frosted) glass front, with a hopper window above the door - the only window you can actually open. There is a second but condemned one in the chamber. curtains serve to divide the entrance from the studio so the bypassers don't see you but you can still hear them (there's only little traffic though). There's a police station right across the place, once i got the unpleasant surprise of a horse patrol (!) but there were no sirens or violent actions during the nights. one saturday some neighbors were celebrating until 3am but otherwise it was rather calm.
bath room contains toilet and shower and is spacious enough. the bed is a convertible and surprisingly large and comfortable. once deployed however there is no more space for anything else in the chamber, eg your suitcase, and the doors of the wardrobe cannot be opened.
the studio is very neat and tidy, furnished with taste, and has a lot of nice little details (eg the lighting). the kitchen is small yet fully equiped (look for the coffee machine hidden in the white cupboard next to the entry).
communication with Anais was ok, the WeHost guy Jules got quickly annoyed because i was late (stuck on the bus).
so if you don't mind having the street right outside your kitchen, then this is a nice flat to spend a (working) week.
