The appartement is very well located, also with good underground and bus lines connections, and our room was really nice and clean when we arrived, so thank you very much.
On the other hand, the place was very noisy. There are people living permanently there, who are screaming all day long, so it is difficult to take some rest after a day exploring London. Even, some people is waking up everyday before 7:00 am (I suppose to go to work), what means also noise until they leave the appartement. Furthermore, we found a guy who was playing the violin since 9:00 pm until 10:30 pm all the nights we stayed there.
Of course, during my life I shared apartments with roomies, and I know that if you want, you can be respectful with the others and taking into your account that you are not the only one living there.
Further, the WiFi connection was not the best. We stayed 1 day long without any internet (don't know why) and the rest of the days the signal was really slow.
Finally, I would say that cleaning was acceptable for a shared apartment, in common areas. But some days the toilet for example was not so clean, without toilet paper, etc.
I think the intention of Lisa to get a great apartment is the best, but I consider that these kind of conditions should be known for the host (maybe are unknown) and guests.
