The apartment is great and as described in the posting. A lot of reviews commented it was noisy but we don't find it that noisy. Extremely near southwark stn and very walkable to waterloo stn which makes travelling very convenient. Toilets are great with good pressure and heating.
Only 2 downsides to this place. All the beds are super soft. They kind of sink in when you lie down so it's kind of back-breaking after the first 2 nights. The other is the many flights of narrow staircase. You practically need to climb stairs whenever you leave your room to toilet or living or kitchen. It's difficult if you have big luggages as well.m

Be careful with the doors. I guess it is for security reasons that the doors and gate autolock after they close. One of my friend had to leave earlier for her flight and while handling her luggages, the door close behind her and her bag was still in the apartment. She had no key and could not return to the apartment.
However, overall it's great value for money. Would recommend staying here!
