As others have described it before, the place is very nice. The light, the views, and the number of possibilities its spaces create are its main features. It is also quite well decorated and quite functional. Its location is, I would say, uncomfortable. The Uber driver could not even find it. It is also quite far from the nearest subway (and via streets and stairs that make it an adventure that can only be accomplished by professional weight-lifters if you are carrying luggage). (I managed to get check-in instructions before the check-in day after begging a bit so that I could plan things in advance--which turned out to be necessary). It should also be noticed that the place is _not_ located in Alfama despite the (deceiving) indication in the official title and description of the listing ("Gorgeous River View in charming Alfama"). It is in Graca.
There are two types of significant problems with this place: (1) nobody has lived in this place and, most importantly, (2) it is poorly run by a company called "GuestReady" or "Gazelle" (I still do not know which one). The apartment seems to have been created just for tourists--with its consequent implications. A good number of very basic things (that would never be missing is somebody lived there) are missing: no light switch that can be reached from the bed, no bedside table, no light in the terrace or in the "living room" area in the bedroom, no place to put the shampoo while you shower (except the floor, which you cannot reach because there is no room in the shower to bend or crouch), no rack to place the dishes as you wash them.... The worst problem is, however, the company that runs the apartment. Communication with them is slow, impersonal, and inefficient. A lot of e-mails are necessary for anybody to address or focus on questions or problems. You never know with whom you are talking (and the person quite often has forgotten about the ongoing communication or has not read it). I could not get any names of anyone I was communicating with despite asking for it in several occasions. All this creates a sense of lack of trust and reliability. Nobody out there seems to be either genuinely concerned about anything or following up with you anything. All this became quite clear when a significant problem emerged. It also showed that the company can be quite inefficient when you need them the most. The fridge was not working. My stay was one week. Despite the amount of time and effort wasted on the matter (reporting, explaining, sending pictures), nothing was done to replace it. (I was refunded 50 euros for it, which served to compensate partially for some of the food wasted but not for the extra money spent in eating outside or for the complications of not having it.)
