Generally the stay was good, but it has some major flaws. Firstly, the place is much smaller that it looks on the photos (there are one common narrow room, 2 tiny toilets and bedroom with law roof). Secondly, it is quite cold in the winter time (because there is no constant home heater, we just received small movable heaters which are not enough for cold winter nights and mornings). Thirdly, the comfort of living was not so good due to problems with eletricity, outdated electric sockest, poor quality doors to the toilets and some uninvited ants at the end of our stay (there was no poison in the house so we fought with them with salt :P).
On the other hand, Annibal was the best host we have ever had. He was really helpful, kind and welcomed us with wine and some useful advise about touring in Lisbon. The localisation is perfect - just near the station Rato and 15 minutes distance on foot from the city centre. The kitchen is well equipped (although the electric stoves are quite rusty) and the bed is very comfortable.
