Close to the botanic garden, Royal Crown Hotel offers very comfortable rooms (typical room is about 30 mq), with a sofa, a couple of armchairs, a table, a marble bath, and a little room for your luggage (plus radio and TV service, of course). Baths are a bit old fashioned, but it is a matter of taste. If you are prepared to pay €20 for breakfast, you will have at your disposal a wide selection of foods and drinks. It is worth it if you plan not to eat until evening. The little Hotel restaurant can be a valuable choice, if you are too tired to go outside at evening.
Suggestion: visit the hotel web site for special offers.
