We stayed at Hotel Paradiso Sul Lago for 3 nights in mid September, and we loved our stay! It was very quiet, relaxing and the views were spectacular. We were lucky to have a room with a lake and pool view. The rooms were clean with a comfy bed and nice en-suite bathroom. The hotel staff were really friendly and most helpful - they were always happy to take us to and collect us from the Funicolare (the transport into Como) otherwise it would have been a bit of a walk. We also wanted to go paddle-boarding on the lake, and the staff insisted on making some calls for us to enquire. Nothing was too much for them.
Sadly their kitchen facilities were out of order during our stay so we couldn't eat in their restaurant (which they were also disappointing about), but they were happy to make suggestions for other options which were very nice. The pool was nice, albeit a bit cold(!) but it was lovely to warm up then in the hot tub and have a drink on the terrace.
If you're looking for a place in the 'thick of it' in terms of bustling bars and restaurants, then this is probably isn't for you as it's a bit out of Como. But if you're looking for a nice, quiet, relaxing family run hotel with jaw dropping views and accommodating staff then this place is ideal.
