First of all - i wasnt perfectly clear on my exact checkout time resulting is leaving a mess for the cleaning, which we try not to.
as for the flat - we came in to the check in about an hour late from the time we said we will and they waited for us, showed us the flat and the area, wifi, tours ext.
the flat is well designed, perfect for a single or a couple but crowded for a bigger bunch.
as for kids - if they are small they should be aware of the staircase as it is steep.
we enjoyed it very much and Sofia was in close contact bringing important stuff to our knowledge, things in the area, weather ext.
location is great in the middle of a pubs zone walking distance from what we needed.
