Erder and Remo were friendly hosts who waited for us to check in. Overall the place is good for people on a budget who won't expect too much and are willing to accept compromises.
Good points:
The place was huge enough for 8 people to stay. The location was great, we could reach all the major sights within 30 minutes by public transport. The place was also located in an quiet and seemingly harmonic area. The equipment and facilities met our expectations for the price we paid. The air-conditioned rooms helped to endure the hot nights.
Things that could have been better:
Flaws for us during the stay were the WiFi connection, the mosquitoes (although our windows were closed) and the fact that during our stay the warm water stopped running in the morning of day 3 of 5. The warm water was essential for us. Erder told us to send technicians until the next day morning, however, she wrote me on the next day in the evening that they could not come. It was unfortunate that the technicians couldn't come before we checked out but the cold showers left is feeling unpleasant about our stay. Therefore our overall rating is just "okay".
