The apartment is located in near the city center with a nice view from the balcony on the Lisbon. Self check in was without any issues when following instructions. Sometimes we had a problem to open apartment door with a key but maybe it was just my clumsiness. The only problem I had was that the apartment is located on the 5th floor without any elevator. When you are returning from the city at night it might be sometimes quite challenging to get on the top floor 😀
