Chris's house is lovely. It's a historic, some 500 year old house with lovely & original features. It's very close to the marina and is very spacious - 3 bedrooms and a cute rooftop. The kitchen/dining were quite comfortable as well having all the amenities. My husband and I and our baby spent 5 days here and enjoyed the quiet of Senglea.
Location wise it's a bit remote. All the action is in Valetta which is a 20 mins drive or a quick ferry. The Senglea marina is a 2 mins walking distance, down a few steps. Do note that to get to the house, there are a lot of steps involved as the island has a lot of steps to get to the inner streets. The cars are parked a few blocks away and there walking involved up or downhill, back and forth.
The other thing to note is that the house is on different levels. So the first floor up is the kitchen/dining. Another floor up are two bedrooms. In between the next floor up is a toilet and lastly on the top floor is the other double bedroom. With the baby, this was a bit of a hassle however, if you're fit and up to it, the house is full of original features so it's quite lovely.
Sylvana the housekeeper was wonderful. Super friendly and very easy to reach. Overall, I'd definitely recommend this place for a unique and comfortable stay in Malta!
