The tango flat is a cozy one room apartment. The bathroom is very spacious, which is great for many people getting ready for parties. Transport options are ok and close but expect transport of 45+ min to most destinations. There are lots of groceries stores near by, but not many cafes or restaurants.
The host is very flexible with check in and check out times. We suggest to ask for the code to the key box at check in, to avoid waiting if the host is late. We also had access to 3 sets of keys which was very practical.
There was müsli and snacks available to us, and the bathroom was also stocked with necessities.
The apartment is right next to the tram track, so it is a bit noisy from the street.
We recommend this place for the price and the care that is put into it to welcome travelers. The best things were the snacks, multiple keys and the check out flexibility. The most negative was a 15 min outside wait for a late host when checking in, and that there was no dishwashing brush.
I recommend this home for travelers attending events in Berlin, who need a practical place to stay during the nights.
