This apartment is nice for 3 or 4 people. We had 4 people in our group. It's on the entry level which is very nice! The living room had a very comfy pull out bed, the single twin room was great for our tall teenager. The apartment is next to the above ground trains. I used earplugs nightly because I'm sensitive to sounds. The earplugs worked fine. No one else in our group noticed the trains which seem to run about every 15 minutes. The trains stop late at night and resume around 600 or 700 in the morning.
The apartment is walking distance to some great small supermarkets, Chicken Cottage [similar to US Kentucky Fried Chicken], and the Famous 3 Kings Pub - the food and drinks are very good there! It is also a short walk to Freddie Mercury's home and Alfred Hitchock's home. :)
