Jose's apartment is located in what was formerly East Berlin and being set on the top floor of a tower block, it offers a stunning view over the city, whatever time of day, it's a magnificent site. It's a short walk from some of Berlin's major attractions, but there's also a metro station right opposite the building, letting you get practically anywhere within minutes.
My girlfriend and I didn't get to meet Jose, but we were greeted by his cleaner, and although she didn't speak English, she was able to show us the basics, and leave us with the keys.
The apartment itself is simple but has everything you need; a decent sized bathroom, a kitchen which overlooks the large living room and an equally large bedroom. There is a private balcony running past the living room and bedroom, where you can smoke (if you're a smoker) and admire the amazing view.
There is a LIDL supermarket and a few other grocery shops a few minutes walk from the building, so you don't have far to go for your day to day essentials.
We visited during a particularly cold march, but the apartments central heating kept us cosy on the colder nights.
Just a note for anyone with allergies: The apartment features feather pillows on the bed and sofa, so if you suffer with allergies I'd recommend going to the local TKMAXX and buying a cheap hypo-allergenic pillow for about 10€.
