We didn't get to meet Marius, but he was very helpful and communicable remotely.
He kept checking in with us to make sure we'd got the keys, gained access and were happy. He also put drinks and a snack in fridge for us.
The apartment was clean and furnished really nicely.
There are only frosted windows, but it's fine if you're out in city during daylight hours.
The floors and walls are a little thin, but the sounds didn't really disturb us. The street outside can also be noisy, but we didn't have trouble sleeping.
The overall experience was great and Marius was the perfect host.
