We stayed her for three nights in April 2010. In every aspect a very good hotel. Location is a bit far from the centre of Weimar, but it is a nice walk through the park. Very nice bar with friendly staff. We enjoyed sitting there for drinks late at night, coming back from the town. Very good atmosphere.
Nice room with a pretty view, clean. Good amenities.
Only minuspoint was breakfast. It was a busy weekend, so it was a bit of a chaos, but I must say that they handled that very well. There were still some quiet tables in the back and they got everything in order for us in a jiffy.
I would certainly recommend this hotel and would not hesitate going there again in the future. One of the best hotels I know in Germany!

I was attending a wedding of a good friend and i booked this hotel in January 2011, when i arrived i was told at the reception that there was no King Size bed available and i told them i paid and booked the hotel room over four months ago! they said sorry we can just join the single beds for you!

Another friend who arrived and was staying alone got a double bed when she booked single. Plus another couple told us they had a similar issue and when housekeeping showed up to join the beds, the carpet was so dirty below with peanuts, etc, yuck!

They try to sell you everything from Breakfast at 10 Euro a person and Parking from 10 to 12 Euro a day plus Internet from 4.90 Euro an Hour! nothing is included in the price.

I recommend you take breakfast in the city center rather then the hotel.

Overall, very ppor service at reception, no customer orientation even if they made a mistake and they even didn't try to make up for not compling with my confirmed choice of room and paid well in advance.

We booked the hotel by phone directly from within Germany.

On arrival by car, we were faced with a parking lot asking for Euro 10 or more for one night, until a nice young man at the reception told us where we could park for free.

We very much enjoyed Weimar but with regard to the hotel, it did not seeem to be so much 4 Star.

E.g. the carpet in the room was full of stains, the entire bathroom was held in an old, beige colour, TV channels were very limited, coffey/tea making facilities (a standard service all over the world) are only for VIP room guest (!), so we were told, and some senior staff at the reception were too busy to be friendly or willing to serve us.

Basically, the entire hotel is run by interns - which they do reasonably well but this should not be the case.

The hotel is used at a conference hotel with lots of busy groups in attendance, also filling up the breakfast area during work days.

Although the location is nice next to Goethe Park, we would probably look for another place next time.

Oh, did I mention the cold water in the pool?

Preface: internet very expensive, about EUR 8/hour, at a reasonable speed !!!! In times like these, internet should be available for free. We spent a holiday in Cambodia and Thailand this July, and rates per hour were less, with some hotels offering WLAN for free, respectively – unbelievable that the Leonardo trails way behind some Asian standard.
Location: huge hotel, about 1 km out off the center / pedestrian zone of Weimar, along Belvederer Allee, that also takes you to the castle of Belvedere, a couple of minutes away (by car);
hotel in a quiet area with front rooms facing a road, and rear rooms local area with villa-style housing, so quiet.
Parking: garage available, parking outside is about EUR 10 per day, cheaper than an hour of internet ;-(
Front-desk: nice welcome, let us move in at 1215 pm, gave me info on prices for the WLAN on the room, however, not mentioning, that the’cheap’ rate is the very slow rate of transmission.
Room: had #545, off the street; two beds in it, furniture you expect in any hotel, offers some space, everything clean, and quiet ! bathroom needs the one and only adjustment (some black and brown stains between tiles, a few only, though)
Breakfast: disappointing, plates and dishes dominate the buffet, in between that 'warehouse-feeling' some limited variety of food for that type of hotel and standard,
so far the least attractive breakfast buffet we’ve had (görlitz/mercure; dresden/elbflorenz; berlin/kanthotel; leipzig/mercure, see reviews);
Staff: first hotel we’ve been in in the recent days where members of the staff don’t greet guests when passing them (e.g. on floor)
but it was quiet in there !
