We stayed 3 nights at Charlotte's apartment. It is all you need; spacious enough (we were 2) with a very comfy bed (!), shower, living area and kitchen. They thought of everything; small supplies in the kitchen, things you might have forgotten to take with you etc. It's very clean and has great extra's like computer, phone, handy tips and books and washing machines upstairs in the building.
It is a bit noisy, outside and upstairs neighbours, however it's all doable and not too much. The neighbours aren't loud talkers, but you can hear them walk (which they do a lot at 4am) as the floors are squeaking a lot. So it's nothing you can really do about it, but it's not very bad. There are a lot of great coffee shops and bars and restaurants in the neighbourhood, which is very nice.
The communication could have been a bit better, as it seemed bit chaotic and last minute. But Charlotte is very nice and easy going, although we haven't met her in person unfortunately.
