The flat was small but absolutely perfect with a very well stocked kitchen area. Miguel was an accomodating host who even allowed us to check out late with no fuss at all, and was happy to offer suggestions of what to do in the city. The location was brilliant with the train station, taxis, local shops, restaurants etc all withing walking distance (Lisbon is hilly though - wear flat shoes!) The only one small down side was that the week we stayed there were builders doing work in the flat above between about 8am to 6/7pm, this was fine for us as we were out all day, but would have been a problem if we had a child with us.
If you are going to Lisbon I would 100% stay here, and I will use thgis flat if I return :)
