I would highly recommends this place. Adams place is super cozy and functional. I lived here for a month and half. It's located on high street (still is pretty quit to live in) and is next to Swiss Cottage underground station and hence is very easy to get to anywhere in the city. It located close to restaurants, banks, post office and multiple grocery stores which makes for a very convenient stay. The place has all the things you would need a long term stay including a very large closet, dresser and a table. It has a small kitchenette along with a small fridge. The place also has a very good wifi connection if you plan to work from home. Most importantly, it's in a very safe neighborhood.
Adam's super nice and replies back immediately to messages and requests. He even came downstairs to receive me and carried my luggage to the room. He has kept the place super clean and easy to use.
All in all, it's value for money.
