Marie is quite helpful and welcome person, she even provided us tickets for a public transport and allowed my son to play with toys of hers.
Regarding the flat - it is nice and cozy, however I have a feeling that the renovation was not finished at that time. For example we were confused when did not find shower curtain and towel hooks in the bathroom.
One thing you may want to take into consideration is the bed in the bedroom may be treated as a hard one. From my side I was completely fine with it, however my wife was not shared my optimism about the bed.
