Fernando is a very enthusiastic and welcoming host. Very knoledgeable about Madrid and very prompt to respond to any communication.
The flat is very cosy, if a little small (no storage space whatsover), every single piece of furniture matches and the flat is overall well designed for short stays.
The location is fantastic, very central, away from the touristic areas, but walking distance from the main attractions.
The only issues are the fifth floor walk up (Fernando helped us taking up the luggage, very kind of him) and the temperature due to it being a loft flat with only one electric heater.
The kitchen is well stocked with utensils, however we never used it as there are many nice places to eat around.
