That's all good and well unless you want to take a shower during the daylight in the summer. Just make sure that your apartment has water all the time, and you will enjoy Montenegro.
Yeah, weather is unusually nice right now, but not in winter: huge winds and rains. In summer it's so hot that you wouldn't want to work.
How is Internet now there? It was not good 2 years ago. Just few providers, bad speed...
