I stayed in the studio for 2 weeks, and it had what I needed. The location was really good - close to the metro and plenty of supermarkets nearby. And I was really happy about how quiet it was in the evening and at night.
Also, I was happily surprised that there were both a small washing machine and a microwave.
The place is small, so for two people, it would be too small - for me at least. The wifi was good and stable. The communication with both Susana and Luise was perfect, before, during, and after my stay. Great hosts.
