We really enjoyed our stay at the apartment of John. Even though we didn't met him, the communication was excellent. He gave us tips and pro actively asked if he could do something to make our stay even more pleasant. The check-in process is easy. Just know that you have to take a lot of stairs to go to the 5th floor. Although there is a elevator, it is really small and basic so we preferred to take the stairs. The location of the apartment is great. At walking distance from central station and also from all the tourist attractions. We only had to take the metro to Atomium and the European Parliament. We would definitely recommend to stay at this apartment!
