We have mixed feelings about this flat. I'll try to itemize the good and bad points, so to let others form their own opinions.

THE GOOD:
1. The location is excellent. We could walk everywhere, and buses and streetcars are only a 7 minute-walk away. There is a terrific coffeeshop for breakfast a couple of minutes away. And it's quiet.
2. The flat is clean, even if it's a bit shabby. The kitchen alcove is tiny but really has everything you could possibly want, if you are planning to cook.
3. The internet worked well.
4. There was enough hot water for one person to shower leisurely, and twenty minutes later there was enough for the next person.
5. Luis was very responsive (on Whats App), fixed things that needed fixing immediately and even had a look around to find something I thought I had lost in the flat.
6. The bed is VERY comfortable.

THE BAD:
1. The flat is a bit shabby. It's fine and comfortable, but for the price it would be nice if there was a proper sofa.
2. The toilet is located IN the shower. Seriously. There are shower curtains to keep the toilet from getting wet, but it's annoying to have to walk in a wet shower to the toilet.
3. The 30 Euro late-fee. I asked Luis about it before we booked and he said it was to cover the cost of taxi for him to get home. Luis, however, did not meet us - a friend of his who lives locally did. Even though the 30 Euro was not used for anyone to take a cab home, it was still not refunded. Luis made all sorts of excuses why the late-fee is still applicable. I felt like Luis took advantage of us.

In summary: I wouldn't book this flat as a first choice, but it's definitely an acceptable option.
