The location of this apartment is excellent and means you can explore a great deal of the city whilst still being close to your accommodation. However, being in the city centre means it is where all the life is so you will definitely need to bring earplugs if you want a good night's sleep.
The extremity of negativity in the reviews is unfounded as the apartment is very clean with a very comfy bed and does look just like the photos, albeit somewhat aged.
The only niggle we had was that it is a completely no frills accommodation and there seemed to be a total lack of attention to detail in basic areas such as providing coffee/milk etc.
A good, reasonably priced option if you want to be central. But seriously- bring earplugs you won't regret it.
