Amazing place, stylish with great clean bathroom. Haven't met the hosts myself but we spoke on the phone to get the directions etc and all was 100%.
Studio is in a secure complex on the 4th floor (with elevator)
Location is close to one of the Metro stations and with easy access to couple bars and shops. For most attractions you have to take the Metro.
We needed to be close to Forum Karlin and this place served this purpose like a charm!
Overall 10/10
One "bad" thing to mention that some people may find useful: there are two beds, a reclined sofa and a double bed in the attic. If you are two single people you are fine but two people in the bed in the attic may sometimes be an issue as on one side the ceiling is really low ;-)
Didn't bother us at all but it is worth mentioning, besides that the place is absolute amazing value for money!!!
