After walking around sightseeing Lisbon we came back at 7pm and our room was not cleaned. Apparently by mistake instead of the sign " ready to be cleaned" we left the sign " come back later" that for the staff of the hotel just means "don't clean my room". There are keycard so they could easely understand if someone was in. there should be a manager double checking if everything is done but they left the housekeeper go without cleaning our room. The conclusion is that the room was not cleaned.
Just choose another place.

The hotel is really close to everything, just around the corner from Baixa-Chiado metro station and a few minutes' walk from the main sights. The staff were polite and helpful and the breakfast was decent.

I stayed at the 7 Hotel in October 2019. This boutique hotel is in an excellent location and great for walking to restaurants and shops. It is also very close to many of the sights and meeting points for tours. The staff was very friendly and helpful and gave us many delicious restaurant recommendations. Please note, not all of the rooms are exterior facing, I had a TINY interior room. I could barely move around the bed, but it was enough for me. It was extremely loud because the walls are super thin and you can hear people in the hallway or going in and out of their rooms. Overall, it is a perfectly situated boutique hotel, you just won't get too much restful sleep.
