Overall the appartment is nice, good location for tube and buses and had the amount af space we needed as a family of six travelling together, but there was also a lot of defects. For example the sleeping sofa wasn't very comfortable and one of the matresses in the other rooms was really poor and you could feel all the springs through when you laid on the bed. When we arrived the floor was very sticky, as if they haven't used soap when cleaning the floor, the rest was cleaned ok. When we tried to turn on the heating in one of the bathrooms the light and power went off in the rest of the apartment - luckily my dad, who I was travelling with, is an electrician, so he knew how to fix it, but we could not turn on the heat for the rest of the trip. The dishwashing machine didn't work, and when we contacted our cantact-person he said he would give it a look when we left. We had to do dishes by hand all week, which took a lot of time compared to we expected to use the dishwashing machine. The washing machine for clothes had a very bad smell so we didn't use it. The wi-fi was very bad and sometimes it didn't work at all.
We think it was a bit too expensive for a week with all of these defects, but if you're just staying for a two nights you might not mind.
