My family and I spent 5 nights at Tomas's place and it was fabulous. The house is in a quiet neighbourhood and is very clean, functional and the well maintained. There was enough space for my family (6 people including 2 children) to run around. The is a nice yard/desk at the house with a trampoline where children can play.
The walk to the train station is a bit long and takes about 25 min to get to central Stockholm.
The only issue with the house was that there is no air-conditioning and only 2 small fans. Since our visit was timed with the ongoing heat wave in Sweden, it was quite uncomfortable to sleep at night and opening the windows etc was a necessity. Maybe this was a one off due to the heatwave and should probably not be a problem at other times of the year.
Didn't meet the host as he was traveling but he was great over the phone/email. And very meticulous with the welcome guide that he had left for us.
Would definitely stay here again and would recommend it to other people.
