The hotel is located a 5 minute walk from the Altona metro. A day ticket for the central area which includes the airport for family of 5 is €12 !
We stayed in the hotel for 3 nights in April 2018. The cost was good by Hamburg standards.
It does not have air con and we found it rather hot sometimes and the controls are not very effective.
Our flat screen medium sized TV had one English news channel. The wifi worked well on all of our devices as did out roaming when out and about in Hamburg.
Facilities included a large king bed and a single, TV, fridge, chairs, wardrobe etc. There was a decent sized bathroom with an effective shower. Toilet, etc. A hair dryer was provided.
There was no lift.
The staff were generally friendly and helpful. I reported a broken light bulb but it was never repaired.
Breakfast was from 7 to 10 and a typical but good quality continental offering was available. Tea/coffee/juice, boiled eggs, some fruit, natural yogurt, selection of breads and cold meets, cereals, etc. Great.
All in all I would give them 9 out of 10 and would stay there again provided it was not at peak season as far as temperature was concerned.
