Martina was great. To-the-point, friendly, informative, knowledgeable and interesting (though the latter point is not really relevant).
The location is also great, a couple of minutes walk from the main station. It is so nice not to have to carry luggage for miles. The 'hood is not at all touristy. The building is very old (14th century, I think Martina said), which is a treat. If you aim to be noisy or if the folks in the other room (yes, this is a shared apartment) are noisy, you will hear everything. Keys in locks, doors moving, as well as human-generated noises. The accomodation is pretty basic, but that was fine by me. Especially at that price. I had a great stay. It was odd that the shower cubicle does not close (one panel out of four appears to be missing), so one has to direct the water jets with great care or mop the floor.
A great improvement would be an extractor fan in the bathroom, as odors and humidity linger.
