Tony and Sonya were very welcoming.
The coordination with my arrival and the provision of the keys were a bit off, but ended up well. The day of my departure the person who they trustedly assigned to pick me up at 4:30am at the appartment to take me to the airport arrived one hour later and I missed my flight, I had to buy a new ticket to go to Barcelona, a very unfortunate event that was not under Tony and Sonya control but ended up leaving a sour flavor to the experience.
The taxi driver was called Bruno, a very irresponsible person -> Do not go for this service, call an Uber or a regular taxi to go to the airport before the Metro opens (6:30am).
It was a great experience overall.
