We stayed as a family of 4. Overall really great experience.
The apartment is not very big, but well designed, so that the space gets used to its maximum. Nespresso coffee machine with capsules, and some cereals was a great addition too!
The location is not at the historical center, but very convenient transportation to everywhere. Grocery store, and various restaurants are very close too.
One thing to improve is checkin instructions. There are 2 code boxes that you need to use. First is outside the building, and if you arrive at darkness, or not very tall, could be a little challenging to use. Then you get a key to the entrance door and it took us a minute or two to find where was the lock for it (its was not one of the door locks, but on the side wall), as there were no instructions about this. Finally the door lock we had troubles to open too, as the instructions indicated the wrong direction it should be turned to... So it took us may be 15 minutes to get into the apartment for the first time.
Another minor issue was the lack of the detergent for a washer. As a family staying for a week, we had to do laundry. I was very surprised when did not find the detergent. When I asked the host, I was referred to the nearby store to buy it. Even though it did not add much to our expenses, I find this really annoying to have to buy a box of detergent to use for just 2-3 loads...
Yet, the issues were minor, and the apartment and the location were both really great. We would stay again any time!
