Helena is very available and communicative person. She made us easily prepare our arrival to her place. She also made many suggestions: restaurants and bars.
Her place is very clean and tidy.
And for sure the location is really very convenient. We were close to all the places we wanted to visit and there were no transport needed.
We still think that Helena's place is perfect for maybe one night if you are two and longer stay if you are a single traveller as they are already 3 persons living in the appartement.
