Thomas' apartment in Montmartre was an excellent stay for a week in Paris.
It is well located to the hills around Montmartre and also easily connected on multiple metro lines through Blanche and Place de Clichy to all the main tourist sights closer to the river in under 30 minutes. Montmartre itself is a great neighbourhood with plenty of restaurant options.
The apartment itself was well appointed for shorter stays, with heating, fast Internet, TV, small kitchen, washing machine and fridge. At the time of writing, there was also a computer monitor for those that want to work remotely. Additionally, the apartment was very quiet despite its central location as it faces an internal courtyard rather than the street.
Thomas was very responsive and have great communication - organising check-in and check-out was very quick and efficient.
