MoCo house in Senglea/L-Isla was an amazing option for us (I traveled there with my parents) to stay in a local area without many tourists and where, if behaving respectfully, locals let you blend in quite smoothly in their way of living.
Niki and her friends were always helpful (before and during our stay) and really open to solve any issues that we might have or find, from checking in and out arrangements to little technical aspects.
The house is gorgeous, very well taken care of, with a fully equipped kitchen and a glorious terrace. Just the (beautiful) 2nd floor suite room has aircon, but all the other rooms have quite powerful fans and that felt enough for our end-of-summer stay.
Just beware of the 3/4 floors and the stairs if you travel with someone who might find that hard. It's a traditional town house with lots of stairs, so some personal organisation might be needed when deciding going up and down (to the terrace or downstairs) in order not to keep yourself continuously on the stairs. Apart from that, I'd totally recommend the house to anyone wanting to live for a few days in one of the most authentic spots on the whole island and among local Maltese people.
Thank you / Grazzi, Niki!
