The apartment is big enough if it's only used for sleeping. We liked the bed, the shower, and the location near to the riverside. We were disappointed about the level of cleanliness (hair and dust on floor and furniture, cobwebs in the corners) but our host arranged a refund. The WiFi was unstable and some necessary things were missing such as shampoo (there was only soap), toilet brush, coffee capsules (as in the pictures) or a second lamp next to the bed.
Though, the check-in was easy (an early check-in was not possible unfortunately) and the communication was quick and good.
