We've stayed at Toni's apartment for 4 nights. We were 2 couples and it was perfect. We had definitely enough space! The apartment has everything we needed to enjoy our stay! Everything was clean, the beds were really comfy, fresh towels and hot water, good WLAN, clean kitchen tools and stuff for dish washing.
The communication with Toni was great, also his friend, who showed us the apartment was really nice und helpful!
The locations is just the best! You really don't need public transportation to get around, because everything is walking distance! And if you need to take the metro, it's just 5 mins walk away!
We'll definitely recommend this apartment to everybody! :)
