Tim's flat is in a nice, safe area. As many reviewers have mentioned there are quite a few narrow, steep stairs... not a problem but good to know in advance. Also, the flat does show some wear and tear from the photos, but it is still pretty cozy.
We had several issues including a problem with the radiators and a dripping faucet, as well as minor inconveniences like no handsoap and dirty dishes in the kitchen when we arrived. I believe Tim did his best to remedy these situations, but they took a lot longer to resolve than I would have liked. Thankfully we were mostly only at the flat to sleep, so it worked out okay.
