The apartment is cosy and in a very central location, perfect for tourists! You can easily walk to the main city attractions or take the metro at one of the nearby stations. The decoration is nice and everything is clean and in good state. The welcome drinks are a nice touch too! You can also store your luggage at their office if you want to stay longer in the city after checking out.
The internet is not very fast, but perfectly usable for browsing and email. We had bad luck with the first shower, though, because hot water ran out after 2 minutes... We had to finish it with cold water. The next day was good, though, so I guess it was really a one-time thing. Just be careful not too leave the water running for too long, because you can feel the maximum temperature dropping as time passes (small water cylinder, perhaps?).
All in all, it was a very pleasant experience!
