Everything was great about the place - the loft was very stylish and clean, the location was in the walking distance to the pier as well as the city centre (and pretty much everything! The host provided everything we needed from bed sheets and towels to even portable Wi-Fi. The recommendations of bars and restaurants were also very helpful - the places were indeed very good!
However, there is only one BUT - the soundproofing of the flat is not very great and as the it is located on one of the main streets of Lisbon, some nights we couldn't sleep because of the noise from the outside. We could literally hear people sing songs and laugh under our windows at 3AM. Therefore, I wouldn't recommend the place to those travelling with kids.
Otherwise, the place is wonderful!
