We stayed at Daniel's flat as a group of 8 for two days in February 2018. Generally, we were satisfied with the accommodation. It was really clean and looked reconstructed. There was no dust. The rooms were spacious however the main room which includes a kitchen and a dining room was a little bit small for 8 people. It is just a small detail but other than that everything was totally fine.
Daniel was always available on a phone although when we met him in person to check in he looked like he was rushing somewhere so he talked really quickly. But he was still nice.
I also would recommend this place for families. It is a quiet neighborhood but not far from a city center.
