The location is amazing: it is a short walk to Apolonia train station. It makes the trip from and to the airport very easy and quick. Apolonia was also great for taking a train to Porto. There is a steep climb from the station to the flat but the steepest part is short and the rest is fine even for a person like me who never does any exercise. The Square of Commerce is a pleasant stroll away through the most picturesque and partly pedestrianised route across Alfama. No steep climbs here. The flea market is a couple blocks away. The flat is small but surprisingly well organised and has all the basics covered. The flat is on the first floor and gets lots of light from the floor to ceiling windows with wooden shutters. The air conditioning works well. Space is limited! I would not recommend a group of 4 to stay here but technically you could fit in 4 as an experiment. As with many Alfama houses, this one is old, the stairs are narrow and steep and people who are seriously overweight or those with some mobility issues should look elsewhere. I thought the bathroom had a somewhat funny smell (mostly from cleaning products but not only) but my husband who is normally much more sensitive said there was nothing of the kind. It can occasionally get noisy(ish) outside from fellow tourists in the neighbouring houses if you are not in luck, but the area itself is quiet and there are no bars or pubs in the immediate vicinity. Shutting the windows helps block the noise quite well and we could sleep well. Overall, a good solid choice if you want to be in Alfama on a budget.
