Our evenings on the patio enjoying a bottle of wine were wonderful! It is definitely the best part of this property!
As others have mentioned, the "upstairs" is a makeshift room with short ceilings and wobbly stairs. This was not a problem for our children, but it would not be desirable for an adult.
There is quite a bit of street noise as the apartment is on a peninsula so the traffic wraps around the two sides and is very noisy! There was another guest in the adjacent apartment on our last night and we could hear every word they spoke, all of their snoring, and everytime they turned in their bed...so you may want to bring ear plugs when you stay here.
Also - I somehow missed the memo about a 300€ cash deposit upon arrival, & unfortunately we hadn't gotten any euros yet. Fortunately, we were able to use our US dollars for the deposit, but anyone who stays here - come better prepared than we did. You will also need to hand over 90€ cash when you arrive for cleaning. Fortunately, we were able to pay the additional cleaning fee when we left after we had exchanged our US dollars for euros.
We are accustomed to always taking our shoes off in the house. At this property, we realized after walking around barefoot in the evenings that our feet were black from the floors - so you may want to bring separate house shoes if you stay here.
If you have a car, be prepared to park and walk a ways to the apartment.
Lastly, always watch your food on the patio as the seagulls are hungry
