We stayed there for two nights in a double room, facing the street.

The bedroom and bathroom were spacious, super comfortable, warm and extremely clean.

The buffer breakfast is generous.

The service is personal and efficient.

The location is convenient with many restaurants nearby.

Strongly recommended.

We stayed for two nights, with a double room and a twin room. Spacious rooms and bathrooms.
Our first night was pretty much ruined by a music festival one block away that lasted until 3.15 a.m. The hotel cannot help that much although exterior soundproofing is very minimal (as everywhere in Peru), and they might have avoided the rooms on top floss facing the festival.
The second night was good.
Heaters in the rooms which is not a luxury in winter.
The hotel appears to support environmental action around lake Titicaca. One recommendation in that regard: cut down the size of the unnecessarily large towels. Saves water, energy, and soap.
