My stay at Monica's home was great, very convenient location, you just have to take the 160 bus to Gullmarsplan and then combine with the green lines metro to T-Centralen. In half an hour or less you reach central station. The room was as it was mentioned in the post. I couldn't meet Monica, unluckily, but she always responded very quickly all my inquiries, thank you very much for that! A friend of her received me the first day and he was really nice in welcome me offering a cup of coffee and suggesting me some sights to visit in the city. Overall, I will definitively stay again at Monica's apt if I have the chance to return one day to Stockholm.
