Romina is very nice and helpful (thanks for the pick up on the airport). Everything was exactly like on the pictures; I didn't miss anything. Her house is very good located, you need 10 minutes to reach EC-School, and 15 for ESE/ETI. There is a bus stop (Bus no.16 from St.Julians/Sliema/Valetta) just few steps away, it's great in case you are tired from walking. There are few small shops around the corner.
Take care that you hear every sound inside the house (also from outside). But it didn't disturb me much, because everything is getting quiet around 10-11pm - except for the weekends :)
Enjoy your stay!
