In short: Rent this apartment. Stop looking and pull the trigger. This is the 5th AB&B I've rented in this area and by far my favorite.
I had already been travelling for a month before I made it to this unit. This was the first rental that actually felt like a home. Tastefully decorated and lacked the tackiness of furniture/art that was purchased cheaply just to fill space.
3 big wins in my book: 1) Soft sheets. They didn't feel cheap and itchy. 2) Comfortable couch which made for a relaxing experience when lounging in the living room. 3) Water pressure! This is something I find significantly lacking in a lot of places I've rented. The shower had great water pressure and was hot within seconds.
The bottle of wine waiting for me when I first stepped in helped to set the ambiance. With chocolates on the pillow and assorted drinks in the refrigerator, I felt like I came to visit a friend who put a good deal of effort into preparing the place for my arrival. You don't need to speak with the hosts to know they are also travellers. It was evident via the atmosphere.
Location puts you close enough to the fun, without having to listen to all the racket when it's time to turn in.
