We spent 3 nights in this flat with 6 persons (3 couples).
The check-in was as described, only a few steps from Campen Town in the office we could leave our luggage. Returning at 3pm we got the key (only one was available for a group of 6 unfortunately.) The address of the flat was not the same as mentioned in the advert, but it seemed to be right around the corner. We received there after a short tube ride and a 10min walk from Old Street Station. The area around is nice. There are a lot of restaurants, bars and clubs. A lot of younger people going out there in the evening. The building seems to be safe. We needed a chip to get into it and a code for the elevator to get to our floor. The flat is very big and has a nice night-view. There is not too much traffic noice to hear during the night. Also no noice from other neigbours to hear. Unfortunately it was not very well cleaned. The kitchen and the bathrooms urgently need an all-round cleaning! We were also missing some kitchen towels and toiletpaper. The kitchen we did not used at all for cooking or eating. We just had some drinks there and used the freeze. The toilet seat in the second bathroom upstairs was broken and had to be used very carefully. In the bathroom downstairs the water run constantly when we arrived. One of our friends repaired this in the best possible way. The bedrooms are big and had enough space to put our stuff. The beds were clean and quite comfortable. Also towels were available for everybody.
The location of the flat is quite nice. The Old Street Station is not far away and also Liverpool Station can be reached by walking. Furthermore there are different bus stations around. Provided that the flat will be cleaned up carefully and some maintenances and repairs will be taken, I can recommend this appartment for a trip to London! After check-out we could also store our luggage at the office, which was very nice.
