We haven't met Andy, so we can't really say something. TJ was really nice and always asked if we need something.
Our room in the apartment was great and big enough for two. The windows are really thin so it's extremely loud during the night (the city that never sleeps ;) ) so we can highly recommend using earplugs during the night.
You have your private bathroom which is quite nice.
The location of the apartment is perfect as there are many busstops and the metrostation around the corner. Nevertheless we tried to avoid longer walks through the neighbourhood when it got dark as we were scared (we are two young girls). I wanna mention that there was no incident or so, nothing has happened and everything was fine - it was just our personal feeling.
All in all we had a great time in this apartement and we can recommend staying there.
Thank you Andy & TJ !! :)
