Well the Esperanto hotel, this is a gem if you can get a room, I love staying here, especially every time I hope to visit the Spa which is included in the stay (you have to pay for the 25m pool only), there are many saunas and steam rooms, along with a salt water pool which goes outside which is excellent for relaxing in.
In the evening on the sixth floor is a bar and meat restaurant, you pay a fixed fee and are given a Yes/No card and a plate. Servers then come around with 10 different types of meats on a sword, you can keep going and when you've had enough simply turn the card to No (Nein), also included is a huge salad bar where you can help yourself to everything to go with your meal including deserts, it's really good.
In the morning breakfast is fully catered again help yourself and there is a wide selection.
The rooms are clean and comfortable however my one only complaint is the temperature of the room, this is quite hot, there is a temperature control in the room, however even at minimum I found the air vent only acting as a fan, not really cooling the air output, however in order to have all the other excellent things I'm happy to stay again, hopefully I only got a one off room with a faulty air conditioner
