Frank is a real nice person, and the place is really near everything you want to see (even if the Pension isn't that easy to find the first time you arrive).
But I had a big problem: my room was full of flying ant, and as I tried to kill them on the first night, they kept coming over and over (as if they weren't coming from an open window but lived somewhere inside).
I told Frank, and he was really nice to me and asked me to go in the double room if I wanted to: but I wonder, what if that room would have been occupied? Did I have to live with flying ant (which I actually did on the first night?)
I was a little disappointed about my staying.
