The apartment has two desks and one large dinner table, so plenty of space to work at. Very fast internet - great for remote work. It has TV and all the channels, youtube, etc. The bed was comfortable and each room has heating for cold nights / months. Good lighting to read books or work.
It can get hot in the summer but that's typical for Paris where historic buildings do not have air conditioning.
The location is excellent right by the prettiest square in Paris, Place des Vosges, very close to everything, many cafes, shops, markets around. The apartment is in the back so it is very quiet despite many people on the street during the day.
Serge was very responsive when we needed help. I highly recommend it.
