This is a difficult review to write as there were some great things about this apartment and some things were less good. Location is brilliant - just near Isator station and a short walk to Marienplatz. As other guests have noted, the setup is a bit unusual in that it is a basement flat down a partially renovated staircase but it looks out onto a courtyard - across which is an office with several employees working away during office hours. We knew all this and it was fine. The main room and bedroom were very comfortable, beds were excellent and heating in the main room was good. There was enough light coming in through the large courtyard door/windows and metal shutters could be closed for darkness and privacy. It was very quiet too.
Less good things were that on arrival the dryer was full of quite damp linen from the last guests. The bathroom was pretty tiny, there was minimal toilet paper provided, the oven was dirty, the can opener was broken and there was only one small pot (as well as two good frying pans) to cook in. The owner’s responses to questions/issues were slow and late (one came at 1am) so lucky there were no major problems.
