Nelson was very accommodating upon our arrival before check-in time. He let us leave our bags and explore the city while they cleaned the unit for our use. The place is in a perfect spot in Lisbon and very close to everything! Nelson also has some great restaurant recommendations which turned out delicious and fun.
Also, before we arrived he recommended we download MEODrive, a free app you can use for navigation without wifi. This literally was indispensable on our trip and was a great suggestion.
