Pros:
1. Location but do note that Seven Sisters has no step free access (so you'll have to carry your bags up a some stairs)
2. Kitchen has good cooking facilities.
3. Washer & Dryer (but perhaps a manual should be given on how to use it).
4. Cleanliness
Cons
1. There is 3 flights of steep steps. So being on the top room and carrying a large luggage was far from ideal, especially the stairs were steep.
2. Water pressure in the bathroom was low.
3. The room was pretty warm, for those staying in the spring and summer, it probably needs a fan to be installed.
Ironically, outside was about 11-18 Celcius but the room was warm (the heater was NOT switched on, so no idea why though).
4. Be careful on the surroundings as many drunks that try to approach you for money from the station to the flat. Just beware of them and try to avoid any communication with them.
