The host: Very organized, available and friendly.
The bed: Mattress protector present. additional padded blankets available to make it softer if desired, which we used and it was very comfortable. The only downside (to the whole place really) is that the slat base can be quite loud (creaky). But if you're not a tosser and turner, or get up a bunch of times throughout the night, or are a heavy sleeper than it's fine.
The shower: good hot water and decent water pressure. The only thing to note is that they are hose showers that have been mounted rather low (I assume to avoid water getting everywhere), so you need to hold it in one hand, or sit down in the tub, to wash your hair. The tubs were some of the cleanest we've seen for an Airbnb though, so not really an issue.
The view: really awesome. if you're up early you can get a great sunrise. The floor to ceiling windows in the living room and master host a great view of the water.
The location: A block from the metro/bus station, which is convenient during the day. There is a huge mall right next door. If you fancy the windows open you'll often get free live music from the street performers, who are quite good! Windows closed it's very quiet. I can't say I was impressed by the nearby restaurant selections, but there are decent areas a longer walk away. (mind you, we're picky and avoid the tourist spots and chain places)
Other: The WiFi was strong throughout the stay. Place was super clean. Security guards 24/7 are very nice. Loved the layout of the flat with the 2 bedrooms being upstairs away from any living room noise. Plenty of closet space. AC in bedroom worked well (only one we tried).
I'd invest in a unit there if available. 5 Stars.
