Sebastian is a very attentive, helpful, friendly and easy-going host. He provides lots of great tips for your stay in Riva. We do recommend the sailing experience he offers. We did it on our last day and it was a perfect finish. As to the flat there isn't much to say. The flat is located on the upper floor of the building. Depending on the weather conditions, airing the flat can be a little annoying due to the restaurant's kitchen downstairs. Although this is nothing one can hold against Sebastian, it's still part of the deal. Besides that, all the positive feedbacks given so far are true. The flat has everything you need. Also, the private parking close to the flat came in quite handy. On top of that, you can easily reach all the important spots of Riva in no time. We fully recommend this place and wouldn't hesitate to come back.
