The studio was perfect for a week's stay where we only needed a place to sleep and otherwise always spent the day outside. Great price!
A few points to mention though: as others have described, it is very dark in the flat as it is on the ground floor and the windows face the courtyard. When we arrived, we found black short hairs on the bed sheets.... but luckily it had a washing machine and detergent, so we were able to wash the sheets again. Also, there was no bread knife, the kitchen is a bit sparsely equipped and some knives were oily/greasy. It gets very hot during the day, and it's hard to ventilate through the windows.... but for the price and our requirements (place to stay at night) it was OK all in all. We had enough hot water for both and the communication went well.
