We stayed for 3 nights in Sebastian's apartment.
A nice small place, in an area easily accessible with every mean of transport, totally worth of spending some time at.
In the apartment you could find everything you needed, at least for a short period, just like we stayed and get a good sleep to rest, since it was very quiet.
The only downside is the block, which is not very well sustained but this is not something Sebastian can do. As long something was in his hand, he delivered and helped us have a good time there.
I would very easily suggest this apartment to anyone.
