The place was better than we expected.
It had everything we needed for a nice stay - well equiped kitchen, nice and clean bedroom and private bathroom.
It is near the bus station with very good connections - it's easy to explore the island by bus. First we were afraid, since Mgarr is not so close to Valletta, but then we realised Mgarr was the best decision possible. It gives you nice options to explore the island. Nice sandy beaches are very very close and easy to reach by bus - Gnejna, Golden bay...
Stephanie is one of the best hosts we've met. Very responsive and willing to help.
She also keeps some maps and guidebooks of the island, which helped us a lot, since we came to the island completely unprepared:).
We highly recommend Stephanie's place!
