ElPilar's place is pretty much as described/seen in the pictures. It is a well-sized apartment in a good and very central location - 5 mins walk from a central train station with many connections that can take you everywhere.
Our stay was more or less as expected and we enjoyed it overall. Also it's worth mentioning that we went to Berlin during a heat wave and as the house does not have aircon, they provided us with a fan, after we asked for it, in order to make our stay more enjoyable. And this was really appreciated!
The only thing I would say is that there is some room for improvement of the amenities offered, which would made our stay even better!
e.g.
- the toilet paper as well as the hand soap finished after the first couple of days and we had to replace them ourselves
- while we were 4 of us we were only provided with 2 hand towels, as this is their policy for 4 people, and we were not given the 2 extra towels when we asked for them
All in all it is a basic and pleasant apartment from where you can easily explore the city!
