The staff at the Altis Belem were superb. Our original room wasn’t comfortable so the manager provided a complementary room upgrade to the river view. The view was beautiful from the large balcony we enjoyed watching the sail boats and ships on the river. The particular room had no wall separating the sleeping area from the bathroom so better suited for couples or solo travelers. The bed was very comfortable we got a great night sleep! We did not realize until our second night that the hotel also offered free breakfast and the breakfast was delicious with a variety of offerings from real fruit, pastries, and a chef to make eggs your way. Make sure to get a thorough list of the hotel offerings as they are plentiful. Some of the furnishings in the hotel room appeared dated and needed modernization like usb outlets next to the bed and more convenient placement of light switches
The hotel location is ideal for most tourists. Right next to the Belém tower and a short walk to Patisserie de Belem
Regarding the Spa, I only booked an appointment for a manicure and pedicure and though I did not enjoy that experience I hear the other spa facilities like the gym, pool and massages are enjoyable.
Overall, I would stay here again on a solo visit to Lisbon. The staff are absolutely fantastic and they made me feel comfortable in their hotel.
