I thoroughly enjoyed my stay at Matthew's apartment.
The place is brand new, the building is nice and modern and had all the amenities we needed.
It is located in a quiet neighborhood, about 40 minutes from Valletta by bus, with a car you can get there in 10/20 minutes.
I particularly appreciated the fast response time by Matthew, the 100 Mbit internet, the extra bed and bathroom and very spacious living room. With air-con it would be a real gem but it's still very nice as is.
I'm happy with what I got and I'd have no problem recommending it.
