My sister and her family (2 adults, 2 teens) stayed at Carmelos place for a couple of nights. They found Carmelo super charming and welcoming and especially at the arrival evening where he pretty unexpected served them some super tasty lasagne was a big hit. Cleaning could be improved in the flat and they ended up leaving one night earlier due to lots of noise. The 4 person room basically does not work for 4 persons, it only has the space for the beds on the floor - and with guests in the other room as well its not really a flat for 6 persons + host at the same time - unless you really like to que at the toilet:-)
Area is nice and with only 5-10 mins walk to public transport.
