We stayed for 2 days in Resilience and Franco's place and our stay was very good ! Perfect place for 2 days in Madrid. The house was clean and cute, it is true that it was humid at first but there is a machine for that and it works very well! Out host was answering our messages very quickly so the communication was good! The location is very close by walk to every touristic locations, so we visited the city efficiently and quickly.
I think the only negative things :
The neighbors are a bit loud
The neighborhood after 8pm can be a bit scary (nothing happen tho! Just the feeling)
Overall everything was good! I recommend the place and will definitly come back if I have the chance :)
