Isabela is a very friendly host and quick to respond to questions. Also the location of the flat is great. However, there are a few things that I found quite disappointing.
The first thing I noticed as I entered the flat was that all the cupboards and closets were locked. This meant there was nowhere I could put my clothes and I just left them on top of a cupboard. The second thing I noticed was that the place was really very cluttered. I had to move a stack of boxes and a bag of empty soda bottles from under the desk before I could sit at it. Unfortunately the only chair available for sitting at the desk was a fold-out chair. Because the description of the flat mentions it being furnished with high quality furniture, I expected all of the furniture to be good. However, apart from the chair, I also found the bed and the sofa quite uncomfortable. The sofa is a pull-out sofa and when you sit on it, it starts to shift and the pillows move forward, causing you to slide off. The mattress on the bed is quite thin and I noticed it really didn't support my back properly. Sadly, I didn't sleep well for a single night.
Summarizing I would give the flat five stars for its responsive host and the location, but two for the appartement itself, mostly because of the bed and the lack of a comfortable place to sit.
