I spent only one night at the Splendide Royal for business and I really enjoyed my short stay there.
First, the hotel is very well located, with a superb view over the lake.
Staff is really helpful, knowledgeable and very welcoming.
Finally, I highly recommend the breakfast there which offers a lot of choices, fresh orange juices, excellent pastries, etc.
In fact, I would not look into booking another hotel next time I am going to Lugano !
