The house proved to be just as amazing as the write-up suggested. It was amazing to stay in a place that is centuries old and yet which has been brought up to date in terms of facilities. The addition of air-conditioning in the two bedrooms was welcome as we were so lucky with unbroken sunshine during our stay.
I could not believe how close the house is to everything we needed. Minutes from Mdina and within walking distance of places like the catacombs that we had been looking forward to seeing. Although the house is well equipped for cooking and entertaining we spent most of our time outdoors and there are a good range of nice places to eat and drink, again all within walking distance. We hired a car and generally had no problem parking close to the house, either in the car park at the end of the road, or alternatively in 'the Ditch' - parking spaces near the Roman villa, underneath the walls of Mdina. Parking at both is free, but it is the done thing to tip a euro to the person who will be on duty helping people to find parking spaces. We also found the local bus services very good, often with services running until quite late in the evening. We travelled to Valetta by bus, since every one rightly warned us about traffic and parking, and it was great, with services every few minutes taking around 20 minutes to the centre of the capital - and all buses accepting contactless payment for the 2 euro flat fare.
One word of caution - the three otherwise very well equipped en-suite bathrooms do not have points in which to plug-in electric toothbrushes or shavers, so if you use them make sure they are fully charged before you arrive.
