It's a nice bright and spacious flat, spotlessly clean, and with everything we needed. The air conditioners in each room also warm the air which was efficient at heating the space as it was quite chilly for our stay. The beds were comfortable and the linen was lovely. The location is great. There is a breakfast cafe next door which was rather hit and miss on the food and the service, but handy for the first morning until we had sussed out the area. The drains were smelling a bit in the flat during our visit, apparently due to the tides(?), which hopefully has been resolved. I would agree with the comments about the noisy tram directly outside both bedrooms and sitting room as the flat is on the 1st floor and the trams can be old and noisy as they rattle past. Not ideal if you're a light sleeper, but otherwise it's a great place. Lisbon is a wonderful city and Sofia is very responsive in communications.
