We stayed to nights at Serenellas place. The location was indeed very quiet and nice, a little up the stairs where there are no cars or noisy mopeds :)
Serenella was always very quick with communication and gave us perfect instructions for the check-in and out.
Everything was as described. We had a little breakfast the first day. For me personally the bed is just too small for two people and not very comfy, but that's just me. All in all we had a nice stay.
