1) Fully remote
2) About 30 minutes away by public transport or bike.
3) Not too bad, I enjoy it. But it's nice knowing it'll someday end, otherwise I'd seek out some middle-ground (e.g. co-working space). I can't see myself ever enjoying full-remote or full-office permanently. I'd love to work at the office 2 or 3 days a week. Without the commute, the mandatory grooming to be presentable, and the eating and such I do at home during reading / passive meetings etc, I feel there's a bit more time left and I have more energy to be extraverted with my people of choice after work. Rather than be forced 5 days a week to socially interact with people I happen to work with, and be drained after I get home. I like office friends, just not 5 days a week.
4) Listed main pros above. Cons are that I feel I was part of a company more, spoke to way more people than I worked with directly, at the office. Those relationships continue WFH, but not for long. If I'd started at a new job from home, I'd miss out on a lot of contacts, both social and professional. Another pro is that I find myself exercising more and destressing more at home. Few of us can be productive for 8 hours. So we're often productive 5 hours. Then spend 3 hours talking, getting coffee, browsing the news, sending a friend a quick meme on our phone. At the office however a lot of that time is kind of wasted, it's 'fast food' content. Whereas at home, sometimes I take a 45 minute lunch break, grab some food from the fridge and watch a nice episode of a detective. Then get back to work. My unproductive time is more valuable and purposeful, less aimless.
5) No, in hindsight it was easy to see Covid-19 lasting all year. We kind of all said it. But there were also various signals that said otherwise. Some countries got a hold on it and opened up after. Other countries had successive lockdown/open-up waves, the situation kept normalising to some extent. But if I knew what I know now (western-europe would begin the pandemic in lockdown and end the year in lockdown), and my manager did too, I could've made the case to move to another country and WFH. I'd rather have been stuck in say Taiwan or China as of the summer, than Europe. Way cheaper, way more fun, way safer, and just generally a nice adventure. Time zones would've been a challenge. But no, I stayed home (western-europe). I'd have way more energy working from home, knowing at 5-6PM I could head out to a nice restaurant, get some drinks, go to a comedy club, visit the museum next evening... than just being stuck at home all evening and working the next day.
6) Yes I recommend it, but we still have a long way to go culture-wise. I'd hate to WFH in a company that doesn't actively facilitate it. Most companies got a big cultural headstart this year, but we're not there yet.
