Locanda Castagnola is a family run hotel with rooms in a large, older house. The room itself was small but big enough for the two of us. We had a double bed with a tv (which didn't work - or we couldnt' figure out how it worked) with a table, 2 chairs and a little closer. The bathroom was also small but big enough with a toilet, sink, and modern shower. The size of the room wasn't important as we did not spend much time inside. What was important was the cleanliness of the room and the room was very clean. We had a nice corner room with a gorgeous view of the Lake. The location of the hotel is up a mountain - but easily accessible from the train station, only 10 minutes away by bus. The location was wonderful because we were in city center within 10 minutes but also halfway to Mount Bre which has a gorgeous panoramic view of the city and various trails for you hike lovers.
The staff was very friendly and accommodating. The only downside was that the person who checked us in did not speak English when the website said that English was one of the languages spoken. Thankfully she spoke Spanish. Since it is a family run hotel, there are times when the front door is locked because they are cleaning the rooms. There was no problem because they had a door bell and also had a sign with both the office phone number as well as a mobile phone number. Once we called the mobile phone, Angela came down and helped us immediately.
There is internet in the building however you need to ask for the code. I would suggest asking for the code when you check in because it is difficult to find someone in the hotel in the evening.
Even with the front desk door closed, we had 24 hour access through the "real" entrance of the house. When you check in, they give you the code which lets you in 24/7.
The room was a great deal for Ticino and I would go back.
