Positive notes: Jan was always answered our questions and the house is in a very good location. Madrid is beautiful!
Negative notes: the bathroom drain keeps filling up constantly and at night it is also annoying. The fridge makes a lot of noise at night (it is a one-room apartment). The electrical sockets are all away from the bed and this is essential. The air conditioner which cannot be used at night in the summer - for condominium rules - (for tourists like us who only stay there at night) in a flat on the last and fourth floor where the greenhouse effect is created in the summer and it is very hot (30/35 degrees in the shade during the da), is not acceptable. We were only notified of this on the day of arrival!
