Our stay in Lisbon was all the better for staying in Siggi's apartment! The reasons for this were several. Firstly, its convenient location being a few minutes walk to the centre, in a quiet back street, very little disturbance at night, situated on the ground floor,that was so good after walking most of the day, up and down the hills (and steps). Secondly, the apartment was so very comfortable, well equipped and had we wished to cook the gadgets were there. It felt very much like home from home. Finally, Siggi's welcome was great, we arrived mid evening but this didn't deter Siggi's greeting he met us off the the aerobus,taking us first to a local restaurant, then a mini walking tour of the immediate area and then an introduction of the apartment. Gave us the keys and left us to do our own thing, with the reassurance that he was only a phone call away.
We both overdid the walking but SO enjoyed our stay and would be happy to recommend this apartment to anyone who wished to have a city break in Lisbon. I would add that I hope to return next year.
