We were a group of 5 adults including 1 elderly. We found the apparent very stylish and clean. Beds are comfortable. The area is not the prettiest at night, but very close to city centre (and subway, that we never used as we walked all the time). Very convenient to have free street parking close by.
Small details : breakfast was not included for us, even if stated in the description - later Marco explained that the reason was we had a discount - this came as a surprise to us as it wasn't mentioned before. Check this when you book.
As the apartment is close by to the subway tracks, you can actually feel some trembling from the subway (especially in the upper part of the apartment - main sleeping area). Half of us found it quite disturbing, so our sleep quality wasn't the best.
Other than that, Marco was very nice an polite and we had a nice stay here.
