We staryed at Marco's place for 3 nights. I had told him that we would arrive early in the morning, and since he had replied "no problem", I had assumed we would be able to check-in in the morning. However, apparently some details had been lost in translation and we were able to finally get the key to the apartment around noon, which is still better than 4 pm which is the regular check-in time.
The location of the apartment was perfect, close to metro station, and lots of awesome cafes. Especially Ruben's cafe where we got our everyday coffee and croissant fix.
The apartment was a bit cold for me, but overall we had a good stay.
