Ivan was at home to greet us in the evening. Because he lives underneath the apartment, we were in no rush. We hired a car from the airport (which was very cheap and we would recommend) and parking was no problem. Ivan showed us everything, how all the things in the apartment worked and how to use the BBQ outside. Unfortunately it was too cold for that in February but it is certainly a great place in summer. The apartment was quite cold and the gas heater was not very strong so take some warm clothes in winter. The Air conditioning heats the living room, but unfortunately, electricity is very expensive in Malta, so we were advised to use it only when absolutely necessary. We paid 20 € for electricity for 3,5 days - as Ivan says in his description you have to buy an electricity card from him. However, lots of the energy in summer comes from solar heating (water) and gas for the stove in the kitchen and energy saving lamps so in summer you would not need that much. Anyway, still good to know this in advance, we thought.
We traveled with two small children and Ivan kindly organized a baby bed for us. So we put one child in the other room and one child in the baby bed and that worked well. The apartment has an elevator until the 4th floor and then you walk one floor, which was fine with the kids. I think the terrace is also safe for kids in summer, but we spent most of our time inside in the very comfortable seating area. The kitchen did not have enough space for us to sit, but it was ok in the living room. The beds were comfortable and the blankets warm enough.
The kitchen is well equipped for any kind of cooking.
Concerning the location we thought it was really ok to reach it from the airport (10-15 minutes depending on the traffic) and we reached Valetta quickly and took a trip to Gozo island which was really great by car. You can take a ferry with the car and it is not really expensive. A taxi from the airport would have cost us 20€ plus seats for the kids so a rental car turned out cheaper. However, we cannot say anything about the public transport.
Ivan was a very kind host who even greated us with a bottle of wine. I think this was a first in our airbnb trips.
Summary: fine with kids, rental car maybe worthwile, take warm pullovers, bring money for electricity card, Ivan is very nice and helpful. We can recommend the flat.
