Nice hotel close to the main station of Darmstadt. The rooms are good and clean, breakfast is excellent. The staff was very friendly. One thing I missed in my room where coffee/tea facilities, something I was expecting in a Maritim hotel, but there weren't. There's a Vapiano restaurant right accross the street, and the city centre is just 2 to 3 tram/bus stops away. There's a nice pool, but the water was a bit too cold. When visiting Darmstadt one can buy a "Darmstadt card" in the tourist info at Luisenplatz, it's just 6 euro for a day or 9 euro for two days, and it includes free public transport.
