Simon's place is very close to the Tunnelbana and only 3 stations from the city centre, so it's a good location. There are also lots of shops and restaurants nearby. (For people that are very sensitive to noise I recommend bringing earplugs as it can get louder during night time) Simon always answered immediatetly, in general the communication with him was very good, also all the instructions on how to find and get into his apartment.
We were 3 people, but I'd recommend the place for 2 people as it can get a bit cramped otherwise. The one negative thing we noticed was that the apartment didn't seem very clean. Simon himself wasn't there to clean before we arrived he told us, so he had a friend do it.
