The good:
Location is central to everything.
2 bedrooms is nice if you've got kids.
Good/solid wifi.
Marcos is great, and provides some great tips on things to see.
The bad:
Kitchen is small with minimal bench space. No oven, toaster or plug for sink meant meal prep etc was a bit uncomfortable.
Living room is an internal room, so minimal natural light.
Only one small sofa - just big enough for 2.
Being one floor up - the bedrooms are prone to a fair bit of street noise (there's a restaurant just under the main bedroom windows). Therefore, you really need to close the windows which can make it quite hot. September was still a bit too warm with the windows shut.
Beds and pillows were uncomfortable (too soft) - sore back and neck each morning for both of us unfortunately.
