This hotel is beautiful. Hammocks and reading material provided. Breakfast offered a great selection. You can walk into town, but its a little far and would recommend a taxi or tuk tuk at night after 9pm. Otherwise, it was safe. Apparently those that rob you do so from a "moto" - they moped up to you and take your stuff and then ride off. That never happened and didn't seem to be a threat. You are fairly close to the local market/souk - it's easy to get lost in it. However, you're also close to the "handmade" market which is nice, covered and small.
We are 2 women (girls?) in their early-mid 30's. Hotel had TV, hot water, your own bathroom and serenity. Would recommend going to Cafe Refugio (best coffee ever - get the signature). You'll also meet some other english speakers from around the world who can give excellent advice on where to go for local eats, drinks and shopping. Defintely a must is Hector's Restaurant where you can meet Hector and eat the most delish food you can get in Guatemala - they also have a great wine selection. Frieda's was also good Mexican eats with real guac.
Two days was plenty of time to explore it all - but at the Casa Madeliene, you could probably stay 3 just to enjoy the hotel's many amenities. Have a great time! We did!
