Titisee is a lovely little lakeside town in the Black Forest, and the Maritime is beautifully situated on the lakefront at the end of the main street. Everything you'd need for a relaxing getaway is within walking distance, and it's a lovely drive or train ride to get to many other Black Forest towns.
The hotel hasn't been updated for a couple of decades, but this honestly doesn't take away from the charm at all. We were happily surprised to be given a double room - essentially two rooms with one set up as a bedroom and the other as a sitting room. Each room had a balcony, as well.
Although the beds were small, they were comfortable. The shower stalls were on the small side but had great water pressure.
The breakfast buffet was very nice, although there was some confusion about whether or not the breakfast was included with the room (it was, but check your reservation). The dining room overlooks the lake, and although we didn't eat dinner in the restaurant, the menu looked good.
We did not take advantage of the spa services as we were out exploring the Black Forest, but I would definitely do this on the next trip! We would happily stay here again, hopefully in the warmer summer months.
