Maggie's flat is amazing, we couldn't have asked for a better place!
It's very clean and comfortable and very well equipped with everything you'd need, included snacks and other essentials in the fridge, that was a very appreciated thought.
Walking distance of all the major tourist sights.
About hot water, we were 3 and we didn't experience any problems with the shower, just avoid long long showers.
Church bells and some road traffic didn't bother us, but if you have light sleep, better have ear plugs.
I'll definitely come back and recommend staying at Maggie's flat!
