We enjoyed Sinan’s place very much, it’s a very secure building and having a lift was wonderful for the 4th floor! The apartment is furnished with everything you need to have a comfortable stay. We enjoyed people watching from the balcony and the view is incredible at night. Easy walking distance to the river, restaurants, bars and shops. Because we had never been to Lisbon, we didn’t know what to expect but an Uber ride from the airport ranged between €8-11, very reasonable. Rides around town were typically €3-7. We did have difficulty getting an Uber for the airport on a weekend early (5:30am - several canceled us) so just a word of caution if you have an early flight. Sinan was very helpful and responded quickly anytime we needed him. We would definitely stay in his apartment again.
