The best part of the flat is the location. It is on the end of a popular touristy street, with easy access to a grocery store, and downhill the whole way to the water (about a mile, nice easy walk). The unit itself is clean and large. The check-in was easy and friendly. A few tips. The washing machine is also a dryer. I learned this on the 3rd load. Very cool, not something one expects from the US. The street is pretty loud. Even though we are on a small side street, you have plenty of street noise. This mattered because we were there on the edge of a heat wave, and had to leave the windows open (there is no A/C and no fans, no ceiling fans). 95% of the time this would not matter, but it was damn hot our week.
The unit has 3 bathrooms. Small, but functional. The biggest and oddest thing was that they only provided ONE bath towel per person. So with two women who expected towels for their hair and body that was a little lame. They did offer for 15 Euro's to send one set of towels, but I could have bought them for a lot less. I did suggest they should have more linens and even blankets. A minor issue, but be prepared. There is only one TV - a small one in the den, where the couch can also double as a bed (but no extra linens). Also, my son didn't figure out the first few times there is a "button" on the shower water adjuster. You need to push the button when you rotate to get HOT water. Cold showers for him!
The building itself is 3 stories. For us in the US a "second floor" unit is up ONE flight, but in Europe where the ground floor is zero, it means two flights. So be aware for this or any unit when having to lug luggage.
The kitchen was well stocked with equipment, we just needed plates and cups, but they had enough for basic cooking. There was plenty of simple breakfast and restaurants within a few hundred feet, so that was nice. And about one block away is the "Dom" hotel. Go up to the bar on the top floor for an amazing view and drinks.
Overall a good stay. Easy access, nice to have some extra room over the hotels.
