I had a great stay at Lucas place and would recommend it. The walking distance to the old center is about 30 minutes, but there is already a lot to see on the way, so it definitely feels less. Especially when you get a quick espresso on the way. The whole apartment was very clean, the communication was very relaxed and easy, and it was no problem that I came back late at night. All in all this is a great place to stay, also for two people.
