We spent 10 nights at Maria appart, it was excellent, everything in the appart is working quit good. It is 15 minutes to istiklal street and around 20 minutes to galata. Selmane is so kind, we arrived late and he waited for us to give us the keys and explained everything.
we encourage couple and friends (no more than 2) to stay at Maria appart.
Two comments, I think it could be more clean specially in terms of blankets, pillows,...
And I think that the kitchen could be better equipped, (no enough forks, knives and spoons... )
