Great location, really accessible by metro, 2 or 3 metro stops from the centre of Paris. There were a number of good supermarkets nearby, the best being the Monoprix near the top of the town, short walk away. Apartment's in a quiet area of Belleville which was nice.
Apartment itself was very light and sunny, had lots of space and was modern and nice. Wifi worked great and the bed was big and comfy.
Kitchen was small and well equipped, but not much space to put your own stuff so had to reorganise it a bit.
Bathroom also good, powerful shower (after waiting a week for the tap to get fixed which was a bit annoying) but it works great now anyway and Dali tried to sort it out as quick as possible.
Dali was very communicative and quick to reply to a text. His sister also very nice when shown around the apartment (as Dali was away).
Had to do some cleaning on arrival as fridge, tiles, toilet and floors weren't very clean and there was a slight ant problem. But apart from that, it's a great studio and enjoyed living there for a month!
