I chilled in garoowe for 2 summers so far. I also stayed in Xamar for 2 weeks. One of the things I noticed is the beggars of Xamar are far more bold and almost demanding compared to Garoowe. Although you can't beat Xamar sea breeze weather.I went to Xamar recently and I can't lie it's actually very nice. Especially around the central Xamar area, Hodan, Buulo Xuubey, number 4 area. I think those regions and Xamar as a whole is very easy for a diaspora to live. You can basically find anything you are used to in the UK over there. Coffee shops, supermarkets high quality restaurants are all available.
However outside of Mogadishu it is kinda difficult to live especially as a diaspora because it isnt really developed like that. You probably won't find any nice restaurants or supermarkets , electricity can just turn off any time and there isn't hot and cold water in demand.
So personally I would say Xamar yes, the rest of Somalia needs to be developed more though.
