On the plus side:
The apartment has the windows facing and inside court, so it’s very quiet.
It’s also very clean and very well equipped (from home appliances you might already see in the photos/description to small stuff that you’d not necesarry expect but do make a difference sometimes: from a moka pot to a manual espresso machine, coffee available either in pads or ground, tea, band aids or makeup remover pads, umbrellas etc).
The mattress is also confortable and the TV has internet access with netflix (you need to have an account obvisously).
As for the location, it’s at 10 minutes (slow) walk from Museum Quarter, there are lots of cafes or small restaurand in the area; Christiana also was very helpful.
On the minus side:
I find the pillows very soft, they aren’t so comfortable if you sleep on the side.
If you stay in the winter, it might by a bit cold for some people as the termostat couldn’t be set over 23°.
Since radiators are behind curtains; you can keep the curtains opened so they won’t block the heat. This wouldn't be much of an issue except that shade rolls are available only in the lobby and bedroom, not in the living room. By keeping the curtains opened, it’s easy to see inside the apartment through it’s big windows.
There are several WiFi networks available to use for guest, but the connectivity is either weak or drops repeatedly, so keep this in mind if you need plan on saving your roaming data plan.
Overall, it is worth to book the place, the minus points are rather annoyances that can be easily overcome depending on the time of visit of your necesities.
For this price and location, I find it hard find a better place, having everything you might need available put at your disposal, in a “residential but still touristy” area at walking distance of to the city center points of interests.
