This place looks cool from the pictures, and is even cooler in real life. In particular, the pictures undersell how light the apartment is (at least in summer). Nice, spacious bedrooms and great design. The location is central, with easy access to the old town and plenty of restaurants and bars right across the street and around the corner, but not overcrowded with tourists. As is to be expected from an apartment located on a busy street, there is some street noise, but nothing overwhelming.
We were 5 in our company, and the apartment would easily house 7. Lots of cutlery, crockery etc. available, as well as fridge, freezer, dishwasher and washing machine. Everything new and everything clean.
The communication, check-in etc. was professional and quick.
In short, if you like hotels, but prefer to have some more space and the possibility to make food, wash clothes etc., this should be a near perfect place.
