We had one night in Edwins apartment and it was really great. It's located quite good (underground in 2 minutes, bikes can also be borrowed), so you can walk to most of the sightseeing highlights of Stockholm. The Vasa museum is only 15 minutes walk away and if you don't mind walking you can also reach any other things. Edwin is a very nice host, he had maps he gave us and explained everything very well. We could use everything in his apartment and he even had towls for us. The kitchen had everything you needed. The internet also worked very good as Edwin also uses it quite often ;)!
We can really recommand this apartment, it is perfect for tqo people wanting to do some sightseeing in Stockholm!
We'll probably come back next year! :)
