Terrific place in Alfama, an older part of Lisboa. The location was A+. The train station is about 4 mins away and the bus station the same. Taxi from the airport to the place is not bad either, it was about 10 euros.
It is a steep climb to the apartment complex and then another steep climb to the apartment itself.
Coming out of the apartment complex if you head up there is a laundromat. Also, in the area near the laundromat there are several restaurants with great food where locals are hanging out for cup of coffee.
Nuno is very responsive, he kept great communication with us throughout our visit to ensure all was great. We had to ask if we could come early to drop off bags because we were in the city earlier than check in time. Nuno accommodated our request, while respecting his guests from the previous night's stay.
