The kitchen area and outside patio were the highlights of this space. We enjoyed breakfast on the back patio in the mornings looking out over the garden area. Bedrooms are both located in the basement, which in the summer is nice because it is cooler, but the stairs leading down might be challenging for some. They are quite steep, even by European standards and they curve making it challenging to bring any luggage downstairs safely.
There are some limitations to the bathroom downstairs, which were explained when we checked in. Not a deal breaker, but will necessitate the use of the upstairs toilet in certain situations. We did not use the shower downstairs so I can't speak to that but the upstairs shower had good water pressure and worked just fine.
Beds were relatively comfortable and we slept reasonably well. The kitchen is very well stocked so if you are planning to actually do some serious cooking, you'll be all set. There are, however many restaurants in the immediate area as well as a metro stop. Despite the many things close by, the apartment was very quiet.
The upstairs was clean but the downstairs could use a bit more attention to detail. I don't know if this was because the rooms hadn't been used in a while and there isn't much natural light to gauge dust/cobwebs or not. The sheets on the beds were clean though.
We didn't have any trouble checking in or out. We were met at the apartment and given a run through of all we needed to know. Our host told us that he was leaving the country the next morning but didn't provide anyone to contact if we had any needs (if we "really needed him, we could call and he would try to help"). Fortunately we didn't need anything but it would have been nice to know there was someone close by in case we did.
