The apartment is in an excellent location in Principe Real with lots of lovely restaurants, coffee shops and bars close by. Bairro Alto is a short walk away and the rest of the city is easily accessible on foot or by public transport. Note that Ubers often work out cheaper than public transport though if you are splitting the fare with a friend!
The apartment itself is very tastefully decorated and has everything you need for a city break, there were only 2 of us but it would definitely accommodate 4 people with no problems as its split level and there are 2 bathrooms.
Bottle of wine on arrival is a nice touch and great to have tea bags and a couple of coffee pods provided.
Our host was easily contactable and was able to give a great tip about where we could store luggage on our last day as our flight was not until late in the evening.
Would definitely recommend this apartment!
